27 Lennart Poettering with major support from Kay Sievers
30 GPLv2+ for all code, except sd-daemon.[ch] and
31 sd-readahead.[ch] which are MIT
34 Linux kernel >= 2.6.39
36 with cgroups (but it's OK to disable all controllers)
37 optional but strongly recommended: autofs4, ipv6
41 PAM >= 1.1.2 (optional)
42 libcryptsetup (optional)
45 tcpwrappers (optional)
47 When you build from git you need the following additional dependencies:
55 make, gcc, and similar tools
57 During runtime you need the following dependencies:
59 util-linux > v2.18 (requires fsck -l, agetty -s)
60 sulogin (from sysvinit-tools, optional but recommended)
64 When systemd-hostnamed is used it is strongly recommended to
65 install nss-myhostname to ensure that in a world of
66 dynamically changing hostnames the hostname stays resolveable
67 under all circumstances. In fact, systemd-hostnamed will warn
68 if nss-myhostname is not installed. Packagers are encouraged to
69 add a dependency on nss-myhostname to the package that
70 includes systemd-hostnamed.
72 Note that D-Bus can link against libsystemd-login.so, which
73 results in a cyclic build dependency. To accomodate for this
74 please build D-Bus without systemd first, then build systemd,
75 then rebuild D-Bus with systemd support.
78 systemd will warn you during boot if /etc/mtab is not a
79 symlink to /proc/mounts. Please ensure that /etc/mtab is a
82 systemd will warn you during boot if /usr is on a different
83 file system than /. While in systemd itself very little will
84 break if /usr is on a separate partition many of its
85 dependencies very likely will break sooner or later in one
86 form or another. For example udev rules tend to refer to
87 binaries in /usr, binaries that link to libraries in /usr or
88 binaries that refer to data files in /usr. Since these
89 breakages are not always directly visible systemd will warn
90 about this, since this kind of file system setup is not really
91 supported anymore by the basic set of Linux OS components.
