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)
66 For systmed-bootchart a kernel with procfs support and several
67 proc output options enabled is required:
73 When building from git you need the following additional dependencies:
86 When systemd-hostnamed is used it is strongly recommended to
87 install nss-myhostname to ensure that in a world of
88 dynamically changing hostnames the hostname stays resolvable
89 under all circumstances. In fact, systemd-hostnamed will warn
90 if nss-myhostname is not installed.
92 Note that D-Bus can link against libsystemd-login.so, which
93 results in a cyclic build dependency. To accommodate for this
94 please build D-Bus without systemd first, then build systemd,
95 then rebuild D-Bus with systemd support.
97 To build HTML documentation for python-systemd using sphinx,
98 please first install systemd (using 'make install'), and then
99 invoke sphinx-build with 'make sphinx-<target>', with <target>
100 being 'html' or 'latexpdf'. If using DESTDIR for installation,
101 pass the same DESTDIR to 'make sphinx-html' invocation.
104 systemd will warn you during boot if /etc/mtab is not a
105 symlink to /proc/mounts. Please ensure that /etc/mtab is a
108 systemd will warn you during boot if /usr is on a different
109 file system than /. While in systemd itself very little will
110 break if /usr is on a separate partition many of its
111 dependencies very likely will break sooner or later in one
112 form or another. For example udev rules tend to refer to
113 binaries in /usr, binaries that link to libraries in /usr or
114 binaries that refer to data files in /usr. Since these
115 breakages are not always directly visible systemd will warn
116 about this, since this kind of file system setup is not really
117 supported anymore by the basic set of Linux OS components.

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