We will now print the name of these processes + when we send SIGKILL to them, since this usually indicates a + problem. + + * If /etc/crypttab refers to password files stored on + configured mount points automatic dependencies will now be + generated to ensure the specific mount is established first + before the key file is attempted to be read. + + * 'systemctl status' will now show information about the + network sockets a socket unit is listening on. + + * 'systemctl status' will also shown information about any + drop-in configuration file for units. (Drop-In configuration + files in this context are files such as + /etc/systemd/systemd/foobar.service.d/*.conf) + + * systemd-cgtop now optionally shows summed up CPU times of + cgroups. Press '%' while running cgtop to switch between + percentage and absolute mode. This is useful to determine + which cgroups use up the most CPU time over the entire + runtime of the system. systemd-cgtop has also been updated + to be 'pipeable' for processing with further shell tools. + + * 'hostnamectl set-hostname' will now allow setting of FQDN + hostnames. + + * The formatting and parsing of time span values has been + changed. The parser now understands fractional expressions + such as "5.5h". The formatter will now output fractional + expressions for all time spans under 1min, i.e. "5.123456s" + rather than "5s 123ms 456us". For time spans under 1s + millisecond values are shown, for those under 1ms + microsecond values are shown. This should greatly improve + all time-related output of systemd. + + * libsystemd-login and libsystemd-journal gained new + functions for querying the poll() events mask and poll() + timeout value for integration into arbitrary event + loops. + + * localectl gained the ability to list available X11 keymaps + (models, layouts, variants, options). + + * 'systemd-analyze dot' gained the ability to filter for + specific units via shell-style globs, to create smaller, + more useful graphs. I.e. it's now possible to create simple + graphs of all the dependencies between only target units, or + of all units that Avahi has dependencies with. + + Contributions from: Cristian Rodríguez, Dr. Tilmann Bubeck, + Harald Hoyer, Holger Hans Peter Freyther, Kay Sievers, Kelly + Anderson, Koen Kooi, Lennart Poettering, Maksim Melnikau, + Marc-Antoine Perennou, Marius Vollmer, Martin Pitt, Michal + Schmidt, Oleksii Shevchuk, Ronny Chevalier, Simon McVittie, + Steven Hiscocks, Thomas Weißschuh, Umut Tezduyar, Václav + Pavlín, Zbigniew Jędrzejewski-Szmek, Łukasz Stelmach + +CHANGES WITH 200: + + * The boot-time readahead implementation for rotating media + will now read the read-ahead data in multiple passes which + consist of all read requests made in equidistant time + intervals. This means instead of strictly reading read-ahead + data in its physical order on disk we now try to find a + middle ground between physical and access time order. + + * /etc/os-release files gained a new BUILD_ID= field for usage + on operating systems that provide continuous builds of OS + images. + + Contributions from: Auke Kok, Eelco Dolstra, Kay Sievers, + Lennart Poettering, Lukas Nykryn, Martin Pitt, Václav Pavlín + William Douglas, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 199: + + * systemd-python gained an API exposing libsystemd-daemon. + + * The SMACK setup logic gained support for uploading CIPSO + security policy. + + * Behaviour of PrivateTmp=, ReadWriteDirectories=, + ReadOnlyDirectories= and InaccessibleDirectories= has + changed. The private /tmp and /var/tmp directories are now + shared by all processes of a service (which means + ExecStartPre= may now leave data in /tmp that ExecStart= of + the same service can still access). When a service is + stopped its temporary directories are immediately deleted + (normal clean-up with tmpfiles is still done in addition to + this though). + + * By default, systemd will now set a couple of sysctl + variables in the kernel: the safe sysrq options are turned + on, IP route verification is turned on, and source routing + disabled. The recently added hardlink and softlink + protection of the kernel is turned on. These settings should + be reasonably safe, and good defaults for all new systems. + + * The predictable network naming logic may now be turned off + with a new kernel command line switch: net.ifnames=0. + + * A new libsystemd-bus module has been added that implements a + pretty complete D-Bus client library. For details see: + + http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html + + * journald will now explicitly flush the journal files to disk + at the latest 5min after each write. The file will then also + be marked offline until the next write. This should increase + reliability in case of a crash. The synchronization delay + can be configured via SyncIntervalSec= in journald.conf. + + * There's a new remote-fs-setup.target unit that can be used + to pull in specific services when at least one remote file + system is to be mounted. + + * There are new targets timers.target and paths.target as + canonical targets to pull user timer and path units in + from. This complements sockets.target with a similar + purpose for socket units. + + * libudev gained a new call udev_device_set_attribute_value() + to set sysfs attributes of a device. + + * The udev daemon now sets the default number of worker + processes executed in parallel based on the number of available + CPUs instead of the amount of available RAM. This is supposed + to provide a more reliable default and limit a too agressive + paralellism for setups with 1000s of devices connected. + + Contributions from: Auke Kok, Colin Walters, Cristian + Rodríguez, Daniel Buch, Dave Reisner, Frederic Crozat, Hannes + Reinecke, Harald Hoyer, Jan Alexander Steffens, Jan + Engelhardt, Josh Triplett, Kay Sievers, Lennart Poettering, + Mantas Mikulėnas, Martin Pitt, Mathieu Bridon, Michael Biebl, + Michal Schmidt, Michal Sekletar, Miklos Vajna, Nathaniel Chen, + Oleksii Shevchuk, Ozan Çağlayan, Thomas Hindoe Paaboel + Andersen, Tollef Fog Heen, Tom Gundersen, Umut Tezduyar, + Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 198: + + * Configuration of unit files may now be extended via drop-in + files without having to edit/override the unit files + themselves. More specifically, if the administrator wants to + change one value for a service file foobar.service he can + now do so by dropping in a configuration snippet into + /etc/systemd/system/foobar.service.d/*.conf. The unit logic + will load all these snippets and apply them on top of the + main unit configuration file, possibly extending or + overriding its settings. Using these drop-in snippets is + generally nicer than the two earlier options for changing + unit files locally: copying the files from + /usr/lib/systemd/system/ to /etc/systemd/system/ and editing + them there; or creating a new file in /etc/systemd/system/ + that incorporates the original one via ".include". Drop-in + snippets into these .d/ directories can be placed in any + directory systemd looks for units in, and the usual + overriding semantics between /usr/lib, /etc and /run apply + for them too. + + * Most unit file settings which take lists of items can now be + reset by assigning the empty string to them. For example, + normally, settings such as Environment=FOO=BAR append a new + environment variable assignment to the environment block, + each time they are used. By assigning Environment= the empty + string the environment block can be reset to empty. This is + particularly useful with the .d/*.conf drop-in snippets + mentioned above, since this adds the ability to reset list + settings from vendor unit files via these drop-ins. + + * systemctl gained a new "list-dependencies" command for + listing the dependencies of a unit recursively. + + * Inhibitors are now honored and listed by "systemctl + suspend", "systemctl poweroff" (and similar) too, not only + GNOME. These commands will also list active sessions by + other users. + + * Resource limits (as exposed by the various control group + controllers) can now be controlled dynamically at runtime + for all units. More specifically, you can now use a command + like "systemctl set-cgroup-attr foobar.service cpu.shares + 2000" to alter the CPU shares a specific service gets. These + settings are stored persistently on disk, and thus allow the + administrator to easily adjust the resource usage of + services with a few simple commands. This dynamic resource + management logic is also available to other programs via the + bus. Almost any kernel cgroup attribute and controller is + supported. + + * systemd-vconsole-setup will now copy all font settings to + all allocated VTs, where it previously applied them only to + the foreground VT. + + * libsystemd-login gained the new sd_session_get_tty() API + call. + + * This release drops support for a few legacy or + distribution-specific LSB facility names when parsing init + scripts: $x-display-manager, $mail-transfer-agent, + $mail-transport-agent, $mail-transfer-agent, $smtp, + $null. Also, the mail-transfer-agent.target unit backing + this has been removed. Distributions which want to retain + compatibility with this should carry the burden for + supporting this themselves and patch support for these back + in, if they really need to. Also, the facilities $syslog and + $local_fs are now ignored, since systemd does not support + early-boot LSB init scripts anymore, and these facilities + are implied anyway for normal services. syslog.target has + also been removed. + + * There are new bus calls on PID1's Manager object for + cancelling jobs, and removing snapshot units. Previously, + both calls were only available on the Job and Snapshot + objects themselves. + + * systemd-journal-gatewayd gained SSL support. + + * The various "environment" files, such as /etc/locale.conf + now support continuation lines with a backslash ("\") as + last character in the line, similar in style (but different) + to how this is supported in shells. + + * For normal user processes the _SYSTEMD_USER_UNIT= field is + now implicitly appended to every log entry logged. systemctl + has been updated to filter by this field when operating on a + user systemd instance. + + * nspawn will now implicitly add the CAP_AUDIT_WRITE and + CAP_AUDIT_CONTROL capabilities to the capabilities set for + the container. This makes it easier to boot unmodified + Fedora systems in a container, which however still requires + audit=0 to be passed on the kernel command line. Auditing in + kernel and userspace is unfortunately still too broken in + context of containers, hence we recommend compiling it out + of the kernel or using audit=0. Hopefully this will be fixed + one day for good in the kernel. + + * nspawn gained the new --bind= and --bind-ro= parameters to + bind mount specific directories from the host into the + container. + + * nspawn will now mount its own devpts file system instance + into the container, in order not to leak pty devices from + the host into the container. + + * systemd will now read the firmware boot time performance + information from the EFI variables, if the used boot loader + supports this, and takes it into account for boot performance + analysis via "systemd-analyze". This is currently supported + only in conjunction with Gummiboot, but could be supported + by other boot loaders too. For details see: + + http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface + + * A new generator has been added that automatically mounts the + EFI System Partition (ESP) to /boot, if that directory + exists, is empty, and no other file system has been + configured to be mounted there. + + * logind will now send out PrepareForSleep(false) out + unconditionally, after coming back from suspend. This may be + used by applications as asynchronous notification for + system resume events. + + * "systemctl unlock-sessions" has been added, that allows + unlocking the screens of all user sessions at once, similar + how "systemctl lock-sessions" already locked all users + sessions. This is backed by a new D-Bus call UnlockSessions(). + + * "loginctl seat-status" will now show the master device of a + seat. (i.e. the device of a seat that needs to be around for + the seat to be considered available, usually the graphics + card). + + * tmpfiles gained a new "X" line type, that allows + configuration of files and directories (with wildcards) that + shall be excluded from automatic cleanup ("aging"). + + * udev default rules set the device node permissions now only + at "add" events, and do not change them any longer with a + later "change" event. + + * The log messages for lid events and power/sleep keypresses + now carry a message ID. + + * We now have a substantially larger unit test suite, but this + continues to be work in progress. + + * udevadm hwdb gained a new --root= parameter to change the + root directory to operate relative to. + + * logind will now issue a background sync() request to the kernel + early at shutdown, so that dirty buffers are flushed to disk early + instead of at the last moment, in order to optimize shutdown + times a little. + + * A new bootctl tool has been added that is an interface for + certain boot loader operations. This is currently a preview + and is likely to be extended into a small mechanism daemon + like timedated, localed, hostnamed, and can be used by + graphical UIs to enumerate available boot options, and + request boot into firmware operations. + + * systemd-bootchart has been relicensed to LGPLv2.1+ to match + the rest of the package. It also has been updated to work + correctly in initrds. + + * Policykit previously has been runtime optional, and is now + also compile time optional via a configure switch. + + * systemd-analyze has been reimplemented in C. Also "systemctl + dot" has moved into systemd-analyze. + + * "systemctl status" with no further parameters will now print + the status of all active or failed units. + + * Operations such as "systemctl start" can now be executed + with a new mode "--irreversible" which may be used to queue + operations that cannot accidentally be reversed by a later + job queuing. This is by default used to make shutdown + requests more robust. + + * The Python API of systemd now gained a new module for + reading journal files. + + * A new tool kernel-install has been added that can install + kernel images according to the Boot Loader Specification: + + http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec + + * Boot time console output has been improved to provide + animated boot time output for hanging jobs. + + * A new tool systemd-activate has been added which can be used + to test socket activation with, directly from the command + line. This should make it much easier to test and debug + socket activation in daemons. + + * journalctl gained a new "--reverse" (or -r) option to show + journal output in reverse order (i.e. newest line first). + + * journalctl gained a new "--pager-end" (or -e) option to jump + to immediately jump to the end of the journal in the + pager. This is only supported in conjunction with "less". + + * journalctl gained a new "--user-unit=" option, that works + similar to "--unit=" but filters for user units rather than + system units. + + * A number of unit files to ease adoption of systemd in + initrds has been added. This moves some minimal logic from + the various initrd implementations into systemd proper. + + * The journal files are now owned by a new group + "systemd-journal", which exists specifically to allow access + to the journal, and nothing else. Previously, we used the + "adm" group for that, which however possibly covers more + than just journal/log file access. This new group is now + already used by systemd-journal-gatewayd to ensure this + daemon gets access to the journal files and as little else + as possible. Note that "make install" will also set FS ACLs + up for /var/log/journal to give "adm" and "wheel" read + access to it, in addition to "systemd-journal" which owns + the journal files. We recommend that packaging scripts also + add read access to "adm" + "wheel" to /var/log/journal, and + all existing/future journal files. To normal users and + administrators little changes, however packagers need to + ensure to create the "systemd-journal" system group at + package installation time. + + * The systemd-journal-gatewayd now runs as unprivileged user + systemd-journal-gateway:systemd-journal-gateway. Packaging + scripts need to create these system user/group at + installation time. + + * timedated now exposes a new boolean property CanNTP that + indicates whether a local NTP service is available or not. + + * systemd-detect-virt will now also detect xen PVs + + * The pstore file system is now mounted by default, if it is + available. + + * In addition to the SELinux and IMA policies we will now also + load SMACK policies at early boot. + + Contributions from: Adel Gadllah, Aleksander Morgado, Auke + Kok, Ayan George, Bastien Nocera, Colin Walters, Daniel Buch, + Daniel Wallace, Dave Reisner, David Herrmann, David Strauss, + Eelco Dolstra, Enrico Scholz, Frederic Crozat, Harald Hoyer, + Jan Janssen, Jonathan Callen, Kay Sievers, Lennart Poettering, + Lukas Nykryn, Mantas Mikulėnas, Marc-Antoine Perennou, Martin + Pitt, Mauro Dreissig, Max F.

That means you can now trigger a unit + based on a calendar time specification such as "Thu,Fri + 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first + or fifth day of any month of the year 2013, given that it is + a thursday or friday. This brings timer event support + considerably closer to cron's capabilities. For details on + the supported calendar time specification language see + systemd.time(7). + + * udev now supports a number of different naming policies for + network interfaces for predictable names, and a combination + of these policies is now the default. Please see this wiki + document for details: + + http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames + + * Auke Kok's bootchart implementation has been added to the + systemd tree. It's an optional component that can graph the + boot in quite some detail. It's one of the best bootchart + implementations around and minimal in its code and + dependencies. + + * nss-myhostname has been integrated into the systemd source + tree. nss-myhostname guarantees that the local hostname + always stays resolvable via NSS. It has been a weak + requirement of systemd-hostnamed since a long time, and + since its code is actually trivial we decided to just + include it in systemd's source tree. It can be turned off + with a configure switch. + + * The read-ahead logic is now capable of properly detecting + whether a btrfs file system is on SSD or rotating media, in + order to optimize the read-ahead scheme. Previously, it was + only capable of detecting this on traditional file systems + such as ext4. + + * In udev, additional device properties are now read from the + IAB in addition to the OUI database. Also, Bluetooth company + identities are attached to the devices as well. + + * In service files %U may be used as specifier that is + replaced by the configured user name of the service. + + * nspawn may now be invoked without a controlling TTY. This + makes it suitable for invocation as its own service. This + may be used to set up a simple containerized server system + using only core OS tools. + + * systemd and nspawn can now accept socket file descriptors + when they are started for socket activation. This enables + implementation of socket activated nspawn + containers. i.e. think about autospawning an entire OS image + when the first SSH or HTTP connection is received. We expect + that similar functionality will also be added to libvirt-lxc + eventually. + + * journalctl will now suppress ANSI color codes when + presenting log data. + + * systemctl will no longer show control group information for + a unit if a the control group is empty anyway. + + * logind can now automatically suspend/hibernate/shutdown the + system on idle. + + * /etc/machine-info and hostnamed now also expose the chassis + type of the system. This can be used to determine whether + the local system is a laptop, desktop, handset or + tablet. This information may either be configured by the + user/vendor or is automatically determined from ACPI and DMI + information if possible. + + * A number of PolicyKit actions are now bound together with + "imply" rules. This should simplify creating UIs because + many actions will now authenticate similar ones as well. + + * Unit files learnt a new condition ConditionACPower= which + may be used to conditionalize a unit depending on whether an + AC power source is connected or not, of whether the system + is running on battery power. + + * systemctl gained a new "is-failed" verb that may be used in + shell scripts and suchlike to check whether a specific unit + is in the "failed" state. + + * The EnvironmentFile= setting in unit files now supports file + globbing, and can hence be used to easily read a number of + environment files at once. + + * systemd will no longer detect and recognize specific + distributions. All distribution-specific #ifdeffery has been + removed, systemd is now fully generic and + distribution-agnostic. Effectively, not too much is lost as + a lot of the code is still accessible via explicit configure + switches. However, support for some distribution specific + legacy configuration file formats has been dropped. We + recommend distributions to simply adopt the configuration + files everybody else uses now and convert the old + configuration from packaging scripts. Most distributions + already did that. If that's not possible or desirable, + distributions are welcome to forward port the specific + pieces of code locally from the git history. + + * When logging a message about a unit systemd will now always + log the unit name in the message meta data. + + * localectl will now also discover system locale data that is + not stored in locale archives, but directly unpacked. + + * logind will no longer unconditionally use framebuffer + devices as seat masters, i.e. as devices that are required + to be existing before a seat is considered preset. Instead, + it will now look for all devices that are tagged as + "seat-master" in udev. By default framebuffer devices will + be marked as such, but depending on local systems other + devices might be marked as well. This may be used to + integrate graphics cards using closed source drivers (such + as NVidia ones) more nicely into logind. Note however, that + we recommend using the open source NVidia drivers instead, + and no udev rules for the closed-source drivers will be + shipped from us upstream. + + Contributions from: Adam Williamson, Alessandro Crismani, Auke + Kok, Colin Walters, Daniel Wallace, Dave Reisner, David + Herrmann, David Strauss, Dimitrios Apostolou, Eelco Dolstra, + Eric Benoit, Giovanni Campagna, Hannes Reinecke, Henrik + Grindal Bakken, Hermann Gausterer, Kay Sievers, Lennart + Poettering, Lukas Nykryn, Mantas Mikulėnas, Marcel Holtmann, + Martin Pitt, Matthew Monaco, Michael Biebl, Michael Terry, + Michal Schmidt, Michal Sekletar, Michał Bartoszkiewicz, Oleg + Samarin, Pekka Lundstrom, Philip Nilsson, Ramkumar + Ramachandra, Richard Yao, Robert Millan, Sami Kerola, Shawn + Landden, Thomas Hindoe Paaboel Andersen, Thomas Jarosch, + Tollef Fog Heen, Tom Gundersen, Umut Tezduyar, Zbigniew + Jędrzejewski-Szmek + +CHANGES WITH 196: + + * udev gained support for loading additional device properties + from an indexed database that is keyed by vendor/product IDs + and similar device identifiers. For the beginning this + "hwdb" is populated with data from the well-known PCI and + USB database, but also includes PNP, ACPI and OID data. In + the longer run this indexed database shall grow into + becoming the one central database for non-essential + userspace device metadata. Previously, data from the PCI/USB + database was only attached to select devices, since the + lookup was a relatively expensive operation due to O(n) time + complexity (with n being the number of entries in the + database). Since this is now O(1), we decided to add in this + data for all devices where this is available, by + default. Note that the indexed database needs to be rebuilt + when new data files are installed. To achieve this you need + to update your packaging scripts to invoke "udevadm hwdb + --update" after installation of hwdb data files. For + RPM-based distributions we introduced the new + %udev_hwdb_update macro for this purpose. + + * The Journal gained support for the "Message Catalog", an + indexed database to link up additional information with + journal entries. For further details please check: + + http://www.freedesktop.org/wiki/Software/systemd/catalog + + The indexed message catalog database also needs to be + rebuilt after installation of message catalog files. Use + "journalctl --update-catalog" for this. For RPM-based + distributions we introduced the %journal_catalog_update + macro for this purpose. + + * The Python Journal bindings gained support for the standard + Python logging framework. + + * The Journal API gained new functions for checking whether + the underlying file system of a journal file is capable of + properly reporting file change notifications, or whether + applications that want to reflect journal changes "live" + need to recheck journal files continously in appropriate + time intervals. + + * It is now possible to set the "age" field for tmpfiles + entries to 0, indicating that files matching this entry + shall always be removed when the directories are cleaned up. + + * coredumpctl gained a new "gdb" verb which invokes gdb + right-away on the selected coredump. + + * There's now support for "hybrid sleep" on kernels that + support this, in addition to "suspend" and "hibernate". Use + "systemctl hybrid-sleep" to make use of this. + + * logind's HandleSuspendKey= setting (and related settings) + now gained support for a new "lock" setting to simply + request the screen lock on all local sessions, instead of + actually executing a suspend or hibernation. + + * systemd will now mount the EFI variables file system by + default. + + * Socket units now gained support for configuration of the + SMACK security label. + + * timedatectl will now output the time of the last and next + daylight saving change. + + * We dropped support for various legacy and distro-specific + concepts, such as insserv, early-boot SysV services + (i.e. those for non-standard runlevels such as 'b' or 'S') + or ArchLinux /etc/rc.conf support. We recommend the + distributions who still need support this to either continue + to maintain the necessary patches downstream, or find a + different solution. (Talk to us if you have questions!) + + * Various systemd components will now bypass PolicyKit checks + for root and otherwise handle properly if PolicyKit is not + found to be around. This should fix most issues for + PolicyKit-less systems. Quite frankly this should have been + this way since day one. It is absolutely our intention to + make systemd work fine on PolicyKit-less systems, and we + consider it a bug if something doesn't work as it should if + PolicyKit is not around. + + * For embedded systems it is now possible to build udev and + systemd without blkid and/or kmod support. + + * "systemctl switch-root" is now capable of switching root + more than once. I.e. in addition to transitions from the + initrd to the host OS it is now possible to transition to + further OS images from the host. This is useful to implement + offline updating tools. + + * Various other additions have been made to the RPM macros + shipped with systemd. Use %udev_rules_update() after + installing new udev rules files. %_udevhwdbdir, + %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, + %_sysctldir are now available which resolve to the right + directories for packages to place various data files in. + + * journalctl gained the new --full switch (in addition to + --all, to disable ellipsation for long messages. + + Contributions from: Anders Olofsson, Auke Kok, Ben Boeckel, + Colin Walters, Cosimo Cecchi, Daniel Wallace, Dave Reisner, + Eelco Dolstra, Holger Hans Peter Freyther, Kay Sievers, + Chun-Yi Lee, Lekensteyn, Lennart Poettering, Mantas Mikulėnas, + Marti Raudsepp, Martin Pitt, Mauro Dreissig, Michael Biebl, + Michal Schmidt, Michal Sekletar, Miklos Vajna, Nis Martensen, + Oleksii Shevchuk, Olivier Brunel, Ramkumar Ramachandra, Thomas + Bächler, Thomas Hindoe Paaboel Andersen, Tom Gundersen, Tony + Camuso, Umut Tezduyar, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 195: + + * journalctl gained new --since= and --until= switches to + filter by time. It also now supports nice filtering for + units via --unit=/-u. + + * Type=oneshot services may use ExecReload= and do the + right thing. + + * The journal daemon now supports time-based rotation and + vacuuming, in addition to the usual disk-space based + rotation. + + * The journal will now index the available field values for + each field name. This enables clients to show pretty drop + downs of available match values when filtering. The bash + completion of journalctl has been updated + accordingly. journalctl gained a new switch -F to list all + values a certain field takes in the journal database. + + * More service events are now written as structured messages + to the journal, and made recognizable via message IDs. + + * The timedated, localed and hostnamed mini-services which + previously only provided support for changing time, locale + and hostname settings from graphical DEs such as GNOME now + also have a minimal (but very useful) text-based client + utility each. This is probably the nicest way to changing + these settings from the command line now, especially since + it lists available options and is fully integrated with bash + completion. + + * There's now a new tool "systemd-coredumpctl" to list and + extract coredumps from the journal. + + * We now install a README each in /var/log/ and + /etc/rc.d/init.d explaining where the system logs and init + scripts went. This hopefully should help folks who go to + that dirs and look into the otherwise now empty void and + scratch their heads. + + * When user-services are invoked (by systemd --user) the + $MANAGERPID env var is set to the PID of systemd. + + * SIGRTMIN+24 when sent to a --user instance will now result + in immediate termination of systemd. + + * gatewayd received numerous feature additions such as a + "follow" mode, for live syncing and filtering. + + * browse.html now allows filtering and showing detailed + information on specific entries. Keyboard navigation and + mouse screen support has been added. + + * gatewayd/journalctl now supports HTML5/JSON + Server-Sent-Events as output. + + * The SysV init script compatibility logic will now + heuristically determine whether a script supports the + "reload" verb, and only then make this available as + "systemctl reload". + + * "systemctl status --follow" has been removed, use "journalctl + -u" instead. + + * journald.conf's RuntimeMinSize=, PersistentMinSize= settings + have been removed since they are hardly useful to be + configured. + + * And I'd like to take the opportunity to specifically mention + Zbigniew for his great contributions.

Krueger, Zbigniew + Jędrzejewski-Szmek, Сковорода Никита Андреевич + +CHANGES WITH 194: + + * If /etc/vconsole.conf is non-existent or empty we will no + longer load any console font or key map at boot by + default. Instead the kernel defaults will be left + intact. This is definitely the right thing to do, as no + configuration should mean no configuration, and hard-coding + font names that are different on all archs is probably a bad + idea. Also, the kernel default key map and font should be + good enough for most cases anyway, and mostly identical to + the userspace fonts/key maps we previously overloaded them + with. If distributions want to continue to default to a + non-kernel font or key map they should ship a default + /etc/vconsole.conf with the appropriate contents. + + Contributions from: Colin Walters, Daniel J Walsh, Dave + Reisner, Kay Sievers, Lennart Poettering, Lukas Nykryn, Tollef + Fog Heen, Tom Gundersen, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 193: + + * journalctl gained a new --cursor= switch to show entries + starting from the specified location in the journal. + + * We now enforce a size limit on journal entry fields exported + with "-o json" in journalctl. Fields larger than 4K will be + assigned null. This can be turned off with --all. + + * An (optional) journal gateway daemon is now available as + "systemd-journal-gatewayd.service". This service provides + access to the journal via HTTP and JSON. This functionality + will be used to implement live log synchronization in both + pull and push modes, but has various other users too, such + as easy log access for debugging of embedded devices. Right + now it is already useful to retrieve the journal via HTTP: + + # systemctl start systemd-journal-gatewayd.service + # wget http://localhost:19531/entries + + This will download the journal contents in a + /var/log/messages compatible format. The same as JSON: + + # curl -H"Accept: application/json" http://localhost:19531/entries + + This service is also accessible via a web browser where a + single static HTML5 app is served that uses the JSON logic + to enable the user to do some basic browsing of the + journal. This will be extended later on. Here's an example + screenshot of this app in its current state: + + http://0pointer.de/public/journal-gatewayd + + Contributions from: Kay Sievers, Lennart Poettering, Robert + Milasan, Tom Gundersen + +CHANGES WITH 192: + + * The bash completion logic is now available for journalctl + too. + + * We don't mount the "cpuset" controller anymore together with + "cpu" and "cpuacct", as "cpuset" groups generally cannot be + started if no parameters are assigned to it. "cpuset" hence + broke code that assumed it it could create "cpu" groups and + just start them. + + * journalctl -f will now subscribe to terminal size changes, + and line break accordingly. + + Contributions from: Dave Reisner, Kay Sievers, Lennart + Poettering, Lukas Nykrynm, Mirco Tischler, Václav Pavlín + +CHANGES WITH 191: + + * nspawn will now create a symlink /etc/localtime in the + container environment, copying the host's timezone + setting. Previously this has been done via a bind mount, but + since symlinks cannot be bind mounted this has now been + changed to create/update the appropriate symlink. + + * journalctl -n's line number argument is now optional, and + will default to 10 if omitted. + + * journald will now log the maximum size the journal files may + take up on disk. This is particularly useful if the default + built-in logic of determining this parameter from the file + system size is used. Use "systemctl status + systemd-journald.service" to see this information. + + * The multi-seat X wrapper tool has been stripped down. As X + is now capable of enumerating graphics devices via udev in a + seat-aware way the wrapper is not strictly necessary + anymore. A stripped down temporary stop-gap is still shipped + until the upstream display managers have been updated to + fully support the new X logic. Expect this wrapper to be + removed entirely in one of the next releases. + + * HandleSleepKey= in logind.conf has been split up into + HandleSuspendKey= and HandleHibernateKey=. The old setting + is not available anymore. X11 and the kernel are + distuingishing between these keys and we should too. This + also means the inhibition lock for these keys has been split + into two. + + Contributions from: Dave Airlie, Eelco Dolstra, Lennart + Poettering, Lukas Nykryn, Václav Pavlín + +CHANGES WITH 190: + + * Whenever a unit changes state we'll now log this to the + journal and show along the unit's own log output in + "systemctl status". + + * ConditionPathIsMountPoint= can now properly detect bind + mount points too. (Previously, a bind mount of one file + system to another place in the same file system could not be + detected as mount, since they shared struct stat's st_dev + field.) + + * We will now mount the cgroup controllers cpu, cpuacct, + cpuset and the controllers net_cls, net_prio together by + default. + + * nspawn containers will now have a virtualized boot + ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted + over with a randomized ID at container initialization). This + has the effect of making "journalctl -b" do the right thing + in a container. + + * The JSON output journal serialization has been updated not + to generate "endless" list objects anymore, but rather one + JSON object per line. This is more in line how most JSON + parsers expect JSON objects. The new output mode + "json-pretty" has been added to provide similar output, but + neatly aligned for readability by humans. + + * We dropped all explicit sync() invocations in the shutdown + code. The kernel does this implicitly anyway in the kernel + reboot() syscall. halt(8)'s -n option is now a compatibility + no-op. + + * We now support virtualized reboot() in containers, as + supported by newer kernels. We will fall back to exit() if + CAP_SYS_REBOOT is not available to the container. Also, + nspawn makes use of this now and will actually reboot the + container if the containerized OS asks for that. + + * journalctl will only show local log output by default + now. Use --merge (-m) to show remote log output, too. + + * libsystemd-journal gained the new sd_journal_get_usage() + call to determine the current disk usage of all journal + files. This is exposed in the new "journalctl --disk-usage" + command. + + * journald gained a new configuration setting SplitMode= in + journald.conf which may be used to control how user journals + are split off. See journald.conf(5) for details. + + * A new condition type ConditionFileNotEmpty= has been added. + + * tmpfiles' "w" lines now support file globbing, to write + multiple files at once. + + * We added Python bindings for the journal submission + APIs. More Python APIs for a number of selected APIs will + likely follow. Note that we intend to add native bindings + only for the Python language, as we consider it common + enough to deserve bindings shipped within systemd. There are + various projects outside of systemd that provide bindings + for languages such as PHP or Lua. + + * Many conditions will now resolve specifiers such as %i. In + addition, PathChanged= and related directives of .path units + now support specifiers as well. + + * There's now a new RPM macro definition for the system preset + dir: %_presetdir. + + * journald will now warn if it can't foward a message to the + syslog daemon because it's socket is full. + + * timedated will no longer write or process /etc/timezone, + except on Debian. As we do not support late mounted /usr + anymore /etc/localtime always being a symlink is now safe, + and hence the information in /etc/timezone is not necessary + anymore. + + * logind will now always reserve one VT for a text getty (VT6 + by default). Previously if more than 6 X sessions where + started they took up all the VTs with auto-spawned gettys, + so that no text gettys were available anymore. + + * udev will now automatically inform the btrfs kernel logic + about btrfs RAID components showing up. This should make + simple hotplug based btrfs RAID assembly work. + + * PID 1 will now increase its RLIMIT_NOFILE to 64K by default + (but not for its children which will stay at the kernel + default). This should allow setups with a lot more listening + sockets. + + * systemd will now always pass the configured timezone to the + kernel at boot. timedated will do the same when the timezone + is changed. + + * logind's inhibition logic has been updated. By default, + logind will now handle the lid switch, the power and sleep + keys all the time, even in graphical sessions. If DEs want + to handle these events on their own they should take the new + handle-power-key, handle-sleep-key and handle-lid-switch + inhibitors during their runtime. A simple way to achiveve + that is to invoke the DE wrapped in an invocation of: + + systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... + + * Access to unit operations is now checked via SELinux taking + the unit file label and client process label into account. + + * systemd will now notify the administrator in the journal + when he over-mounts a non-empty directory. + + * There are new specifiers that are resolved in unit files, + for the host name (%H), the machine ID (%m) and the boot ID + (%b). + + Contributions from: Allin Cottrell, Auke Kok, Brandon Philips, + Colin Guthrie, Colin Walters, Daniel J Walsh, Dave Reisner, + Eelco Dolstra, Jan Engelhardt, Kay Sievers, Lennart + Poettering, Lucas De Marchi, Lukas Nykryn, Mantas Mikulėnas, + Martin Pitt, Matthias Clasen, Michael Olbrich, Pierre Schmitz, + Shawn Landden, Thomas Hindoe Paaboel Andersen, Tom Gundersen, + Václav Pavlín, Yin Kangkai, Zbigniew Jędrzejewski-Szmek + CHANGES WITH 189: * Support for reading structured kernel messages from @@ -56,7 +1036,7 @@ CHANGES WITH 189: * Services which hit the restart limit will now be placed in a failure state. - Contributions from Bertram Poettering, Dave Reisner, Huang + Contributions from: Bertram Poettering, Dave Reisner, Huang Hang, Kay Sievers, Lennart Poettering, Lukas Nykryn, Martin Pitt, Simon Peeters, Zbigniew Jędrzejewski-Szmek @@ -335,6 +1315,7 @@ CHANGES WITH 186: Shawn Landden, Tom Gundersen CHANGES WITH 185: + * "systemctl help " now shows the man page if one is available. @@ -353,6 +1334,7 @@ CHANGES WITH 185: Matthias Clasen CHANGES WITH 184: + * logind is now capable of (optionally) handling power and sleep keys as well as the lid switch. @@ -369,6 +1351,7 @@ CHANGES WITH 184: Menzel, Shawn Landden, Tero Roponen, Tom Gundersen CHANGES WITH 183: + * Note that we skipped 139 releases here in order to set the new version to something that is greater than both udev's and systemd's most recent version number. @@ -556,6 +1539,7 @@ CHANGES WITH 183: Gundersen CHANGES WITH 44: + * This is mostly a bugfix release * Support optional initialization of the machine ID from the @@ -601,6 +1585,7 @@ CHANGES WITH 44: Reding CHANGES WITH 43: + * This is mostly a bugfix release * systems lacking /etc/os-release are no longer supported. @@ -614,6 +1599,7 @@ CHANGES WITH 43: Biebl CHANGES WITH 42: + * This is an important bugfix release for v41. * Building man pages is now optional which should be useful @@ -635,6 +1621,7 @@ CHANGES WITH 42: Schmidt, Michał Górny, Piotr Drąg CHANGES WITH 41: + * The systemd binary is installed /usr/lib/systemd/systemd now; An existing /sbin/init symlink needs to be adapted with the package update. @@ -662,6 +1649,7 @@ CHANGES WITH 41: William Douglas CHANGES WITH 40: + * This is mostly a bugfix release * We now expose the reason why a service failed in the @@ -680,6 +1668,7 @@ CHANGES WITH 40: Mike Kazantsev, Ray Strode CHANGES WITH 39: + * This is mostly a test release, but incorporates many bugfixes. @@ -737,6 +1726,7 @@ CHANGES WITH 39: Poettering, Michal Schmidt CHANGES WITH 38: + * This is mostly a test release, but incorporates many bugfixes.
