  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         libblkid >= 2.20 (from util-linux) (optional)
  44         libkmod >= 5 (optional)
  45         PAM >= 1.1.2 (optional)
  46         libcryptsetup (optional)
  47         libaudit (optional)
  48         libacl (optional)
  49         libattr (optional)
  50         libselinux (optional)
  51         liblzma (optional)
  52         tcpwrappers (optional)
  53         libgcrypt (optional)
  54         libqrencode (optional)
  55         libmicrohttpd (optional)
  56         libpython (optional)
  57         make, gcc, and similar tools
  58
  59         During runtime you need the following additional dependencies:
  60
  61         util-linux >= v2.19 (requires fsck -l, agetty -s)
  62         sulogin (from util-linux >= 2.22 or sysvinit-tools, optional but recommended)
  63         dracut (optional)
  64
  65         When building from git you need the following additional dependencies:
  66
  67         docbook-xsl
  68         xsltproc
  69         automake
  70         autoconf
  71         libtool
  72         intltool
  73         gperf
  74         gtkdocize (optional)
  75         python (optional)
  76
  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.
  82
  83         Note that D-Bus can link against libsystemd-login.so, which
  84         results in a cyclic build dependency. To accommodate for this
  85         please build D-Bus without systemd first, then build systemd,
  86         then rebuild D-Bus with systemd support.
  87
  88 WARNINGS:
  89         systemd will warn you during boot if /etc/mtab is not a
  90         symlink to /proc/mounts. Please ensure that /etc/mtab is a
  91         proper symlink.
  92
  93         systemd will warn you during boot if /usr is on a different
  94         file system than /. While in systemd itself very little will
  95         break if /usr is on a separate partition many of its
  96         dependencies very likely will break sooner or later in one
  97         form or another. For example udev rules tend to refer to
  98         binaries in /usr, binaries that link to libraries in /usr or
  99         binaries that refer to data files in /usr. Since these
 100         breakages are not always directly visible systemd will warn
 101         about this, since this kind of file system setup is not really
 102         supported anymore by the basic set of Linux OS components.
 103
 104         For more information on this issue consult
 105         http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken
 106
 107         To run systemd under valgrind, compile with VALGRIND defined
 108         (e.g. ./configure CPPFLAGS='... -DVALGRIND=1'). Otherwise,
 109         false positives will be triggered by code which violates
 110         some rules but is actually safe.
