It + is still fully supported to use the udev daemon and tools without + systemd running, like in initramfs or other init systems. Building + udev though, will require the *build* of the systemd tree, but + udev can be properly *run* without systemd. + + * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles + should be used to create dead device nodes as workarounds for broken + subsystems. + + * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is + no longer supported. udev_monitor_new_from_netlink() needs to be + used to subscribe to events. + + * udev: when udevd is started by systemd, processes which are left + behind by forking them off of udev rules, are unconditionally cleaned + up and killed now after the event handling has finished. Services or + daemons must be started as systemd services. Services can be + pulled-in by udev to get started, but they can no longer be directly + forked by udev rules. + + * udev: the daemon binary is called systemd-udevd now and installed + in /usr/lib/systemd/. Standalone builds or non-systemd systems need + to adapt to that, create symlink, or rename the binary after building + it. + + * libudev no longer provides these symbols: + udev_monitor_from_socket() + udev_queue_get_failed_list_entry() + udev_get_{dev,sys,run}_path() + The versions number was bumped and symbol versioning introduced. + + * systemd-loginctl and systemd-journalctl have been renamed + to loginctl and journalctl to match systemctl. + + * The config files: /etc/systemd/systemd-logind.conf and + /etc/systemd/systemd-journald.conf have been renamed to + logind.conf and journald.conf. Package updates should rename + the files to the new names on upgrade. + + * For almost all files the license is now LGPL2.1+, changed + from the previous GPL2.0+. Exceptions are some minor stuff + of udev (which will be changed to LGPL2.1 eventually, too), + and the MIT licensed sd-daemon.[ch] library that is suitable + to be used as drop-in files. + + * systemd and logind now handle system sleep states, in + particulary suspending and hibernating. + + * logind now implements a sleep/shutdown/idle inhibiting logic + suitable for a variety of uses. Soonishly Lennart will blog + about this in more detail. + + * var-run.mount and var-lock.mount are no longer provided + (which prevously bind mounted these directories to their new + places). Distributions which have not converted these + directories to symlinks should consider stealing these files + from git history and add them downstream. + + * We introduced the Documentation= field for units and added + this to all our shipped units. This is useful to make it + easier to explore the boot and the purpose of the various + units. + + * All smaller setup units (such as + systemd-vconsole-setup.service) now detect properly if they + are run in a container and are skipped when + appropriate. This guarantees an entirely noise-free boot in + Linux container environments such as systemd-nspawn. + + * A framework for implementing offline system updates is now + integrated, for details see: + http://freedesktop.org/wiki/Software/systemd/SystemUpdates + + * A new service type Type=idle is available now which helps us + avoiding ugly interleaving of getty output and boot status + messages. + + * There's now a system-wide CapabilityBoundingSet= option to + globally reduce the set of capabilities for the + system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, + CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or + even CAP_NET_ADMIN system-wide for secure systems. + + * There are now system-wide DefaultLimitXXX= options to + globally change the defaults of the various resource limits + for all units started by PID 1. + + * Harald Hoyer's systemd test suite has been integrated into + systemd which allows easy testing of systemd builds in qemu + and nspawn. (This is really awesome! Ask us for details!) + + * The fstab parser is now implemented as generator, not inside + of PID 1 anymore. + + * systemctl will now warn you if .mount units generated from + /etc/fstab are out of date due to changes in fstab that + haven't been read by systemd yet. + + * systemd is now suitable for usage in initrds. Dracut has + already been updated to make use of this. With this in place + initrds get a slight bit faster but primarily are much + easier to introspect and debug since "systemctl status" in + the host system can be used to introspect initrd services, + and the journal from the initrd is kept around too. + + * systemd-delta has been added, a tool to explore differences + between user/admin configuration and vendor defaults. + + * PrivateTmp= now affects both /tmp and /var/tmp. + + * Boot time status messages are now much prettier and feature + proper english language. Booting up systemd has never been + so sexy. + + * Read-ahead pack files now include the inode number of all + files to pre-cache. When the inode changes the pre-caching + is not attempted. This should be nicer to deal with updated + packages which might result in changes of read-ahead + patterns. + + * We now temporaritly lower the kernel's read_ahead_kb variable + when collecting read-ahead data to ensure the kernel's + built-in read-ahead does not add noise to our measurements + of necessary blocks to pre-cache. + + * There's now RequiresMountsFor= to add automatic dependencies + for all mounts necessary for a specific file system path. + + * MountAuto= and SwapAuto= have been removed from + system.conf. Mounting file systems at boot has to take place + in systemd now. + + * nspawn now learned a new switch --uuid= to set the machine + ID on the command line. + + * nspawn now learned the -b switch to automatically search + for an init system. + + * vt102 is now the default TERM for serial TTYs, upgraded from + vt100. + + * systemd-logind now works on VT-less systems. + + * The build tree has been reorganized. The individual + components now have directories of their own. + + * A new condition type ConditionPathIsReadWrite= is now available. + + * nspawn learned the new -C switch to create cgroups for the + container in other hierarchies. + + * We now have support for hardware watchdogs, configurable in + system.conf. + + * The scheduled shutdown logic now has a public API. + + * We now mount /tmp as tmpfs by default, but this can be + masked and /etc/fstab can override it. + + * Since udisks doesn't make use of /media anymore we are not + mounting a tmpfs on it anymore. + + * journalctl gained a new --local switch to only interleave + locally generated journal files. + + * We can now load the IMA policy at boot automatically. + + * The GTK tools have been split off into a systemd-ui. + + Contributions from: Andreas Schwab, Auke Kok, Ayan George, + Colin Guthrie, Daniel Mack, Dave Reisner, David Ward, Elan + Ruusamäe, Frederic Crozat, Gergely Nagy, Guillermo Vidal, + Hannes Reinecke, Harald Hoyer, Javier Jardón, Kay Sievers, + Lennart Poettering, Lucas De Marchi, Léo Gillot-Lamure, + Marc-Antoine Perennou, Martin Pitt, Matthew Monaco, Maxim + A.
