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+, excluding
35 src/udev/libudev* which is LGPLv2.1+
38 Linux kernel >= 2.6.39
40 with cgroups (but it's OK to disable all controllers)
41 optional but strongly recommended: autofs4, ipv6
45 PAM >= 1.1.2 (optional)
46 libcryptsetup (optional)
49 tcpwrappers (optional)
51 When you build from git you need the following additional dependencies:
59 make, gcc, and similar tools
61 During runtime you need the following dependencies:
63 util-linux > v2.18 (requires fsck -l, agetty -s)
64 sulogin (from sysvinit-tools, optional but recommended)
68 When systemd-hostnamed is used it is strongly recommended to
69 install nss-myhostname to ensure that in a world of
70 dynamically changing hostnames the hostname stays resolveable
71 under all circumstances. In fact, systemd-hostnamed will warn
72 if nss-myhostname is not installed. Packagers are encouraged to
73 add a dependency on nss-myhostname to the package that
74 includes systemd-hostnamed.
76 Note that D-Bus can link against libsystemd-login.so, which
77 results in a cyclic build dependency. To accomodate for this
78 please build D-Bus without systemd first, then build systemd,
79 then rebuild D-Bus with systemd support.
82 systemd will warn you during boot if /etc/mtab is not a
83 symlink to /proc/mounts. Please ensure that /etc/mtab is a
86 systemd will warn you during boot if /usr is on a different
87 file system than /. While in systemd itself very little will
88 break if /usr is on a separate partition many of its
89 dependencies very likely will break sooner or later in one
90 form or another. For example udev rules tend to refer to
91 binaries in /usr, binaries that link to libraries in /usr or
92 binaries that refer to data files in /usr. Since these
93 breakages are not always directly visible systemd will warn
94 about this, since this kind of file system setup is not really
95 supported anymore by the basic set of Linux OS components.
