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 PAM >= 1.1.2 (optional)
44 libcryptsetup (optional)
49 tcpwrappers (optional)
51 When you build from git you need the following additional dependencies:
62 make, gcc, and similar tools
64 During runtime you need the following dependencies:
66 util-linux > v2.18 (requires fsck -l, agetty -s)
67 sulogin (from sysvinit-tools, optional but recommended)
70 When systemd-hostnamed is used it is strongly recommended to
71 install nss-myhostname to ensure that in a world of
72 dynamically changing hostnames the hostname stays resolveable
73 under all circumstances. In fact, systemd-hostnamed will warn
74 if nss-myhostname is not installed. Packagers are encouraged to
75 add a dependency on nss-myhostname to the package that
76 includes systemd-hostnamed.
78 Note that D-Bus can link against libsystemd-login.so, which
79 results in a cyclic build dependency. To accommodate for this
80 please build D-Bus without systemd first, then build systemd,
81 then rebuild D-Bus with systemd support.
84 systemd will warn you during boot if /etc/mtab is not a
85 symlink to /proc/mounts. Please ensure that /etc/mtab is a
88 systemd will warn you during boot if /usr is on a different
89 file system than /. While in systemd itself very little will
90 break if /usr is on a separate partition many of its
91 dependencies very likely will break sooner or later in one
92 form or another. For example udev rules tend to refer to
93 binaries in /usr, binaries that link to libraries in /usr or
94 binaries that refer to data files in /usr. Since these
95 breakages are not always directly visible systemd will warn
96 about this, since this kind of file system setup is not really
97 supported anymore by the basic set of Linux OS components.
