36 REQUIREMENTS:
37 Linux kernel >= 2.6.39
38 with devtmpfs
39 with cgroups (but it's OK to disable all controllers)
40 optional but strongly recommended: autofs4, ipv6
41 dbus >= 1.4.0
42 libcap
43 PAM >= 1.1.2 (optional)
44 libcryptsetup (optional)
45 libaudit (optional)
46 libselinux (optional)
47 tcpwrappers (optional)

49 When you build from git you need the following additional dependencies:
50
51 docbook-xsl
52 xsltproc
53 automake
54 autoconf
55 libtool
56 gperf
57 make, gcc, and similar tools
58
59 During runtime you need the following dependencies:
60
61 util-linux > v2.18 (requires fsck -l, agetty -s)
62 sulogin (from sysvinit-tools, optional but recommended)
63 dracut (optional)
64
65 When systemd-hostnamed is used it is strongly recommended to
66 install nss-myhostname to ensure that in a world of
67 dynamically changing hostnames the hostname stays resolveable
68 under all circumstances. In fact, systemd-hostnamed will warn
69 if nss-myhostname is not installed. Packagers are encouraged to
70 add a dependency on nss-myhostname to the package that
71 includes systemd-hostnamed.
72
73 Note that D-Bus can link against libsystemd-login.so, which
74 results in a cyclic build dependency. To accomodate for this
75 please build D-Bus without systemd first, then build systemd,
76 then rebuild D-Bus with systemd support.
77
78 WARNINGS:
79 systemd will warn you during boot if /etc/mtab is not a
80 symlink to /proc/mounts. Please ensure that /etc/mtab is a
81 proper symlink.
82
83 systemd will warn you during boot if /usr is on a different
84 file system than /. While in systemd itself very little will
85 break if /usr is on a separate partition many of its
86 dependencies very likely will break sooner or later in one
87 form or another. For example udev rules tend to refer to
88 binaries in /usr, binaries that link to libraries in /usr or
89 binaries that refer to data files in /usr. Since these
90 breakages are not always directly visible systemd will warn
91 about this, since this kind of file system setup is not really
92 supported anymore by the basic set of Linux OS components.
