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 libblkid >= 2.20 (from util-linux) (optional)
44 libkmod >= 5 (optional)
45 PAM >= 1.1.2 (optional)
46 libcryptsetup (optional)
52 tcpwrappers (optional)
54 libqrencode (optional)
55 libmicrohttpd (optional)
57 make, gcc, and similar tools
59 During runtime you need the following additional dependencies:
61 util-linux >= v2.19 (requires fsck -l, agetty -s)
62 sulogin (from util-linux >= 2.22 or sysvinit-tools, optional but recommended)
65 When building from git you need the following additional dependencies:
77 When systemd-hostnamed is used it is strongly recommended to
78 install nss-myhostname to ensure that in a world of
79 dynamically changing hostnames the hostname stays resolvable
80 under all circumstances. In fact, systemd-hostnamed will warn
81 if nss-myhostname is not installed. Packagers are encouraged to
82 add a dependency on nss-myhostname to the package that
83 includes systemd-hostnamed.
85 Note that D-Bus can link against libsystemd-login.so, which
86 results in a cyclic build dependency. To accommodate for this
87 please build D-Bus without systemd first, then build systemd,
88 then rebuild D-Bus with systemd support.
91 systemd will warn you during boot if /etc/mtab is not a
92 symlink to /proc/mounts. Please ensure that /etc/mtab is a
95 systemd will warn you during boot if /usr is on a different
96 file system than /. While in systemd itself very little will
97 break if /usr is on a separate partition many of its
98 dependencies very likely will break sooner or later in one
99 form or another. For example udev rules tend to refer to
100 binaries in /usr, binaries that link to libraries in /usr or
101 binaries that refer to data files in /usr. Since these
102 breakages are not always directly visible systemd will warn
103 about this, since this kind of file system setup is not really
104 supported anymore by the basic set of Linux OS components.

109 To run systemd under valgrind, compile with VALGRIND defined
110 (e.g. ./configure CPPFLAGS='... -DVALGRIND=1'). Otherwise,
111 false positives will be triggered by code which violates
112 some rules but is actually safe.
