  47         libgcrypt (optional)
  48         libaudit (optional)
  49         libacl (optional)
  50         libattr (optional)

  58         When you build from git you need the following additional dependencies:
  59
  60         docbook-xsl
  61         xsltproc
  62         automake
  63         autoconf
  64         libtool
  65         intltool
  66         gperf
  67         gtkdocize (optional)
  68         python (optional)
  69         make, gcc, and similar tools
  70
  71         During runtime you need the following dependencies:
  72
  73         util-linux > v2.18 (requires fsck -l, agetty -s)
  74         sulogin (from sysvinit-tools, optional but recommended)
  75         dracut (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. Packagers are encouraged to
  82         add a dependency on nss-myhostname to the package that
  83         includes systemd-hostnamed.
  84
  85         Note that D-Bus can link against libsystemd-login.so, which
  86         results in a cyclic build dependency. To accommodate for this
  87         please build D-Bus without systemd first, then build systemd,
  88         then rebuild D-Bus with systemd support.
  89
  90 WARNINGS:
  91         systemd will warn you during boot if /etc/mtab is not a
  92         symlink to /proc/mounts. Please ensure that /etc/mtab is a
  93         proper symlink.
  94
  95         systemd will warn you during boot if /usr is on a different
  96         file system than /. While in systemd itself very little will
  97         break if /usr is on a separate partition many of its
  98         dependencies very likely will break sooner or later in one
  99         form or another. For example udev rules tend to refer to
 100         binaries in /usr, binaries that link to libraries in /usr or
 101         binaries that refer to data files in /usr. Since these
 102         breakages are not always directly visible systemd will warn
 103         about this, since this kind of file system setup is not really
 104         supported anymore by the basic set of Linux OS components.
 105
 106         For more information on this issue consult

 108
 109         To run systemd under valgrind, compile with VALGRIND defined
 110         (e.g. ./configure CPPFLAGS='... -DVALGRIND=1'). Otherwise,
 111         false positives will be triggered by code which violates
 112         some rules but is actually safe.
