  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)
  48
  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         plymouth (optional)
  64         dracut (optional)
  65
  66         When systemd-hostnamed is used it is strongly recommended to
  67         install nss-myhostname to ensure that in a world of
  68         dynamically changing hostnames the hostname stays resolveable
  69         under all circumstances. In fact, systemd-hostnamed will warn
  70         if nss-myhostname is not installed. Packagers are encouraged to
  71         add a dependency on nss-myhostname to the package that
  72         includes systemd-hostnamed.
  73
  74         Note that D-Bus can link against libsystemd-login.so, which
  75         results in a cyclic build dependency. To accomodate for this
  76         please build D-Bus without systemd first, then build systemd,
  77         then rebuild D-Bus with systemd support.
  78
  79 WARNINGS:
  80         systemd will warn you during boot if /etc/mtab is not a
  81         symlink to /proc/mounts. Please ensure that /etc/mtab is a
  82         proper symlink.
  83
  84         systemd will warn you during boot if /usr is on a different
  85         file system than /. While in systemd itself very little will
  86         break if /usr is on a separate partition many of its
  87         dependencies very likely will break sooner or later in one
  88         form or another. For example udev rules tend to refer to
  89         binaries in /usr, binaries that link to libraries in /usr or
  90         binaries that refer to data files in /usr. Since these
  91         breakages are not always directly visible systemd will warn
  92         about this, since this kind of file system setup is not really
  93         supported anymore by the basic set of Linux OS components.
