When you build from git you need the following additional dependencies:

docbook-xsl

xsltproc

automake

autoconf

libtool

intltool

gperf

gtkdocize (optional)

python (optional)

make, gcc, and similar tools

During runtime you need the following dependencies:

util-linux > v2.18 (requires fsck -l, agetty -s)

sulogin (from sysvinit-tools, optional but recommended)

dracut (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. Packagers are encouraged to

add a dependency on nss-myhostname to the package that

includes systemd-hostnamed.

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

http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken

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.
