  32
  33 REQUIREMENTS:
  34         Linux kernel >= 2.6.39
  35                 with devtmpfs
  36                 with cgroups (but it's OK to disable all controllers)
  37                 optional but strongly recommended: autofs4, ipv6
  38         libudev >= 172
  39         dbus >= 1.4.0
  40         libcap
  41         PAM >= 1.1.2 (optional)
  42         libcryptsetup (optional)
  43         libaudit (optional)
  44         libselinux (optional)
  45         tcpwrappers (optional)
  46
  47         When you build from git you need the following additional dependencies:
  48
  49         docbook-xsl
  50         xsltproc
  51         automake
  52         autoconf
  53         libtool
  54         gperf
  55         make, gcc, and similar tools
  56
  57         During runtime you need the following dependencies:
  58
  59         util-linux > v2.18 (requires fsck -l, agetty -s)
  60         sulogin (from sysvinit-tools, optional but recommended)
  61         plymouth (optional)
  62         dracut (optional)
  63
  64         When systemd-hostnamed is used it is strongly recommended to
  65         install nss-myhostname to ensure that in a world of
  66         dynamically changing hostnames the hostname stays resolveable
  67         under all circumstances. In fact, systemd-hostnamed will warn
  68         if nss-myhostname is not installed. Packagers are encouraged to
  69         add a dependency on nss-myhostname to the package that
  70         includes systemd-hostnamed.
  71
  72         Note that D-Bus can link against libsystemd-login.so, which
  73         results in a cyclic build dependency. To accomodate for this
  74         please build D-Bus without systemd first, then build systemd,
  75         then rebuild D-Bus with systemd support.
  76
  77 WARNINGS:
  78         systemd will warn you during boot if /etc/mtab is not a
  79         symlink to /proc/mounts. Please ensure that /etc/mtab is a
  80         proper symlink.
  81
  82         systemd will warn you during boot if /usr is on a different
  83         file system than /. While in systemd itself very little will
  84         break if /usr is on a separate partition many of its
  85         dependencies very likely will break sooner or later in one
  86         form or another. For example udev rules tend to refer to
  87         binaries in /usr, binaries that link to libraries in /usr or
  88         binaries that refer to data files in /usr. Since these
  89         breakages are not always directly visible systemd will warn
  90         about this, since this kind of file system setup is not really
  91         supported anymore by the basic set of Linux OS components.
