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