  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         gtk+ >= 2.20 (optional)
  42         PAM >= 1.1.2 (optional)
  43         libcryptsetup (optional)
  44         libaudit (optional)
  45         libselinux (optional)
  46         tcpwrappers (optional)
  47         libnotify (optional)
  48
  49         When you build from git you need the following additional dependencies:
  50
  51         vala >= 0.10
  52         docbook-xsl
  53         xsltproc
  54         automake
  55         autoconf
  56         libtool
  57         gperf
  58         make, gcc, and similar tools
  59
  60         During runtime you need the following dependencies:
  61
  62         util-linux > v2.18 (requires fsck -l, agetty -s)
  63         sulogin (from sysvinit-tools, optional but recommended)
  64         plymouth (optional)
  65         dracut (optional)
  66
  67         When systemd-hostnamed is used it is strongly recommended to
  68         install nss-myhostname to ensure that in a world of
  69         dynamically changing hostnames the hostname stays resolveable
  70         under all circumstances. In fact, systemd-hostnamed will warn
  71         if nss-myhostname is not installed. Packagers are encouraged to
  72         add a dependency on nss-myhostname to the package that
  73         includes systemd-hostnamed.
  74
  75         Note that D-Bus can link against libsystemd-login.so, which
  76         results in a cyclic build dependency. To accomodate for this
  77         please build D-Bus without systemd first, then build systemd,
  78         then rebuild D-Bus with systemd support.
  79
  80 WARNINGS:
  81         systemd will warn you during boot if /etc/mtab is not a
  82         symlink to /proc/mounts. Please ensure that /etc/mtab is a
  83         proper symlink.
  84
  85         systemd will warn you during boot if /usr is on a different
  86         file system than /. While in systemd itself very little will
  87         break if /usr is on a separate partition many of its
  88         dependencies very likely will break sooner or later in one
  89         form or another. For example udev rules tend to refer to
  90         binaries in /usr, binaries that link to libraries in /usr or
  91         binaries that refer to data files in /usr. Since these
  92         breakages are not always directly visible systemd will warn
  93         about this, since this kind of file system setup is not really
  94         supported anymore by the basic set of Linux OS components.
