  36 REQUIREMENTS:
  37         Linux kernel >= 2.6.39
  38                 with devtmpfs

  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)

  57         When you build from git you need the following additional dependencies:
  58
  59         docbook-xsl
  60         xsltproc
  61         automake
  62         autoconf
  63         libtool
  64         intltool
  65         gperf
  66         gtkdocize (optional)
  67         python (optional)
  68         make, gcc, and similar tools
  69
  70         During runtime you need the following dependencies:
  71
  72         util-linux > v2.18 (requires fsck -l, agetty -s)
  73         sulogin (from sysvinit-tools, optional but recommended)
  74         dracut (optional)
  75
  76         When systemd-hostnamed is used it is strongly recommended to
  77         install nss-myhostname to ensure that in a world of
  78         dynamically changing hostnames the hostname stays resolvable
  79         under all circumstances. In fact, systemd-hostnamed will warn
  80         if nss-myhostname is not installed. Packagers are encouraged to
  81         add a dependency on nss-myhostname to the package that
  82         includes systemd-hostnamed.
  83
  84         Note that D-Bus can link against libsystemd-login.so, which
  85         results in a cyclic build dependency. To accommodate for this
  86         please build D-Bus without systemd first, then build systemd,
  87         then rebuild D-Bus with systemd support.
  88
  89 WARNINGS:
  90         systemd will warn you during boot if /etc/mtab is not a
  91         symlink to /proc/mounts. Please ensure that /etc/mtab is a
  92         proper symlink.
  93
  94         systemd will warn you during boot if /usr is on a different
  95         file system than /. While in systemd itself very little will
  96         break if /usr is on a separate partition many of its
  97         dependencies very likely will break sooner or later in one
  98         form or another. For example udev rules tend to refer to
  99         binaries in /usr, binaries that link to libraries in /usr or
 100         binaries that refer to data files in /usr. Since these
 101         breakages are not always directly visible systemd will warn
 102         about this, since this kind of file system setup is not really
 103         supported anymore by the basic set of Linux OS components.
 104
 105         For more information on this issue consult
 106         http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken
 107
 108         To run systemd under valgrind, compile with VALGRIND defined
 109         (e.g. ./configure CPPFLAGS='... -DVALGRIND=1'). Otherwise,
 110         false positives will be triggered by code which violates
 111         some rules but is actually safe.
