52 When you build from git you need the following additional dependencies:
53
3ede835a
LP
54 docbook-xsl
55 xsltproc
56 automake
57 autoconf
58 libtool
19d5d4cb 59 intltool
b62cfcea 60 gperf
19d5d4cb
ZJS
61 gtkdocize (optional)
62 python (optional)
21bc923a 63 make, gcc, and similar tools
3ede835a
LP
64
65 During runtime you need the following dependencies:
66
c1c8ca81 67 util-linux > v2.18 (requires fsck -l, agetty -s)
21bc923a 68 sulogin (from sysvinit-tools, optional but recommended)
3ede835a 69 dracut (optional)

71 When systemd-hostnamed is used it is strongly recommended to
72 install nss-myhostname to ensure that in a world of
73 dynamically changing hostnames the hostname stays resolveable
74 under all circumstances. In fact, systemd-hostnamed will warn
75 if nss-myhostname is not installed. Packagers are encouraged to
76 add a dependency on nss-myhostname to the package that
77 includes systemd-hostnamed.
78
6705c2df 79 Note that D-Bus can link against libsystemd-login.so, which
49f43d5f 80 results in a cyclic build dependency. To accommodate for this
6705c2df
LP
81 please build D-Bus without systemd first, then build systemd,
82 then rebuild D-Bus with systemd support.

84WARNINGS:
85 systemd will warn you during boot if /etc/mtab is not a
86 symlink to /proc/mounts. Please ensure that /etc/mtab is a
87 proper symlink.
88
89 systemd will warn you during boot if /usr is on a different
90 file system than /. While in systemd itself very little will
ed1c99fc 91 break if /usr is on a separate partition many of its
21bc923a
LP
92 dependencies very likely will break sooner or later in one
93 form or another. For example udev rules tend to refer to
94 binaries in /usr, binaries that link to libraries in /usr or
95 binaries that refer to data files in /usr. Since these
96 breakages are not always directly visible systemd will warn
97 about this, since this kind of file system setup is not really
98 supported anymore by the basic set of Linux OS components.
