32 LGPLv2.1+ for all code
33 - except sd-daemon.[ch] and sd-readahead.[ch] which are MIT
34 - except src/udev/ which is GPLv2.0+
37 Linux kernel >= 2.6.39
39 with cgroups (but it's OK to disable all controllers)
40 optional but strongly recommended: autofs4, ipv6
43 libblkid >= 2.20 (from util-linux) (optional)
44 libkmod >= 5 (optional)
45 PAM >= 1.1.2 (optional)
46 libcryptsetup (optional)
52 tcpwrappers (optional)
54 libqrencode (optional)
55 libmicrohttpd (optional)
57 make, gcc, and similar tools
59 During runtime you need the following additional dependencies:
61 util-linux >= v2.19 (requires fsck -l, agetty -s)
62 sulogin (from util-linux >= 2.22 or sysvinit-tools, optional but recommended)
66 For systmed-bootchart a kernel with procfs support and several
67 proc output options enabled is required:
73 When building from git you need the following additional dependencies:
86 When systemd-hostnamed is used it is strongly recommended to
87 install nss-myhostname to ensure that in a world of
88 dynamically changing hostnames the hostname stays resolvable
89 under all circumstances. In fact, systemd-hostnamed will warn
90 if nss-myhostname is not installed.
92 Note that D-Bus can link against libsystemd-login.so, which
93 results in a cyclic build dependency. To accommodate for this
94 please build D-Bus without systemd first, then build systemd,
95 then rebuild D-Bus with systemd support.
97 To build HTML documentation for python-systemd using sphinx,
98 please first install systemd (using 'make install'), and then
99 invoke sphinx-build with 'make sphinx-<target>', with <target>
100 being 'html' or 'latexpdf'. If using DESTDIR for installation,
101 pass the same DESTDIR to 'make sphinx-html' invocation.
104 During runtime the journal daemon requires the
105 "system-journal" system group to exist. New journal files will
106 be readable by this group (but not writable) which may be used
107 to grant specific users read access.
109 It is also recommended to grant read access to all journal
110 files to the system groups "wheel" and "adm" with a command
111 like the following in the post installation script of the
114 # setfacl -nm g:wheel:rx,d:g:wheel:rx,g:adm:rx,d:g:adm:rx /var/log/journal/
117 systemd will warn you during boot if /etc/mtab is not a
118 symlink to /proc/mounts. Please ensure that /etc/mtab is a
121 systemd will warn you during boot if /usr is on a different
122 file system than /. While in systemd itself very little will
123 break if /usr is on a separate partition many of its
124 dependencies very likely will break sooner or later in one
125 form or another. For example udev rules tend to refer to
126 binaries in /usr, binaries that link to libraries in /usr or
127 binaries that refer to data files in /usr. Since these
128 breakages are not always directly visible systemd will warn
129 about this, since this kind of file system setup is not really
130 supported anymore by the basic set of Linux OS components.

135 To run systemd under valgrind, compile with VALGRIND defined
136 (e.g. ./configure CPPFLAGS='... -DVALGRIND=1'). Otherwise,
137 false positives will be triggered by code which violates
138 some rules but is actually safe.
