30 GPLv2+ for all code, except sd-daemon.[ch] which is MIT
33 Linux kernel >= 2.6.39 (with devtmpfs, cgroups; optional but strongly recommended: autofs4, ipv6)
37 gtk+ >= 2.20 (optional)
38 PAM >= 1.1.2 (optional)
39 libcryptsetup (optional)
42 tcpwrappers (optional)
45 When you build from git you need the following additional dependencies:
54 make, gcc, and similar tools
56 During runtime you need the following dependencies:
58 util-linux > v2.18 (requires fsck -l, agetty -s)
59 sulogin (from sysvinit-tools, optional but recommended)
63 When systemd-hostnamed is used it is strongly recommended to
64 install nss-myhostname to ensure that in a world of
65 dynamically changing hostnames the hostname stays resolveable
66 under all circumstances. In fact, systemd-hostnamed will warn
67 if nss-myhostname is not installed. Packagers are encouraged to
68 add a dependency on nss-myhostname to the package that
69 includes systemd-hostnamed.
71 Note that D-Bus can link against libsystemd-login.so, which
72 results in a cyclic build dependency. To accomodate for this
73 please build D-Bus without systemd first, then build systemd,
74 then rebuild D-Bus with systemd support.
77 systemd will warn you during boot if /etc/mtab is not a
78 symlink to /proc/mounts. Please ensure that /etc/mtab is a
81 systemd will warn you during boot if /usr is on a different
82 file system than /. While in systemd itself very little will
83 break if /usr is on a separate partition many of its
84 dependencies very likely will break sooner or later in one
85 form or another. For example udev rules tend to refer to
86 binaries in /usr, binaries that link to libraries in /usr or
87 binaries that refer to data files in /usr. Since these
88 breakages are not always directly visible systemd will warn
89 about this, since this kind of file system setup is not really
90 supported anymore by the basic set of Linux OS components.
