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