REQUIREMENTS:
|
|
Linux kernel >= 2.6.39
|
|
with devtmpfs
|
|
with cgroups (but it's OK to disable all controllers)
|
|
optional but strongly recommended: autofs4, ipv6
|
|
dbus >= 1.4.0
|
|
libcap
|
|
libblkid >= 2.20 (from util-linux) (optional)
|
|
libkmod >= 5 (optional)
|
|
PAM >= 1.1.2 (optional)
|
|
libcryptsetup (optional)
|
|
libaudit (optional)
|
|
libacl (optional)
|
|
libattr (optional)
|
|
libselinux (optional)
|
|
liblzma (optional)
|
|
tcpwrappers (optional)
|
|
libgcrypt (optional)
|
|
libqrencode (optional)
|
|
libmicrohttpd (optional)
|
|
libpython (optional)
|
|
make, gcc, and similar tools
|
|
|
|
During runtime you need the following additional dependencies:
|
|
|
|
util-linux >= v2.19 (requires fsck -l, agetty -s)
|
|
sulogin (from util-linux >= 2.22 or sysvinit-tools, optional but recommended)
|
|
dracut (optional)
|
|
PolicyKit (optional)
|
|
|
|
When building from git you need the following additional dependencies:
|
|
|
|
docbook-xsl
|
|
xsltproc
|
|
automake
|
|
autoconf
|
|
libtool
|
|
intltool
|
|
gperf
|
|
gtkdocize (optional)
|
|
python (optional)
|
|
|
|
When systemd-hostnamed is used it is strongly recommended to
|
|
install nss-myhostname to ensure that in a world of
|
|
dynamically changing hostnames the hostname stays resolvable
|
|
under all circumstances. In fact, systemd-hostnamed will warn
|
|
if nss-myhostname is not installed.
|
|
|
|
Note that D-Bus can link against libsystemd-login.so, which
|
|
results in a cyclic build dependency. To accommodate for this
|
|
please build D-Bus without systemd first, then build systemd,
|
|
then rebuild D-Bus with systemd support.
|
|
|
|
WARNINGS:
|
|
systemd will warn you during boot if /etc/mtab is not a
|
|
symlink to /proc/mounts. Please ensure that /etc/mtab is a
|
|
proper symlink.
|
|
|
|
systemd will warn you during boot if /usr is on a different
|
|
file system than /. While in systemd itself very little will
|
|
break if /usr is on a separate partition many of its
|
|
dependencies very likely will break sooner or later in one
|
|
form or another. For example udev rules tend to refer to
|
|
binaries in /usr, binaries that link to libraries in /usr or
|
|
binaries that refer to data files in /usr. Since these
|
|
breakages are not always directly visible systemd will warn
|
|
about this, since this kind of file system setup is not really
|
|
supported anymore by the basic set of Linux OS components.
|
|
|
|
For more information on this issue consult

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