36 | REQUIREMENTS: | |
37 | Linux kernel >= 2.6.39 | |
38 | with devtmpfs | |
39 | with cgroups (but it's OK to disable all controllers) | |
40 | optional but strongly recommended: autofs4, ipv6 | |
41 | dbus >= 1.4.0 | |
42 | libcap | |
43 | PAM >= 1.1.2 (optional) | |
44 | libcryptsetup (optional) | |
45 | libaudit (optional) | |
46 | libacl (optional) | |
47 | libselinux (optional) | |
48 | liblzma (optional) | |
49 | tcpwrappers (optional) | |
50 | ||
51 | When you build from git you need the following additional dependencies: | |
52 | ||
53 | docbook-xsl | |
54 | xsltproc | |
55 | automake | |
56 | autoconf | |
57 | libtool | |
58 | intltool | |
59 | gperf | |
60 | gtkdocize (optional) | |
61 | python (optional) | |
62 | make, gcc, and similar tools | |
63 | ||
64 | During runtime you need the following dependencies: | |
65 | ||
66 | util-linux > v2.18 (requires fsck -l, agetty -s) | |
67 | sulogin (from sysvinit-tools, optional but recommended) | |
68 | dracut (optional) | |
69 | ||
70 | When systemd-hostnamed is used it is strongly recommended to | |
71 | install nss-myhostname to ensure that in a world of | |
72 | dynamically changing hostnames the hostname stays resolveable | |
73 | under all circumstances. In fact, systemd-hostnamed will warn | |
74 | if nss-myhostname is not installed. Packagers are encouraged to | |
75 | add a dependency on nss-myhostname to the package that | |
76 | includes systemd-hostnamed. | |
77 | ||
78 | Note that D-Bus can link against libsystemd-login.so, which | |
79 | results in a cyclic build dependency. To accommodate for this | |
80 | please build D-Bus without systemd first, then build systemd, | |
81 | then rebuild D-Bus with systemd support. | |
82 | ||
83 | WARNINGS: | |
84 | systemd will warn you during boot if /etc/mtab is not a | |
85 | symlink to /proc/mounts. Please ensure that /etc/mtab is a | |
86 | proper symlink. | |
87 | ||
88 | systemd will warn you during boot if /usr is on a different | |
89 | file system than /. While in systemd itself very little will | |
90 | break if /usr is on a separate partition many of its | |
91 | dependencies very likely will break sooner or later in one | |
92 | form or another. For example udev rules tend to refer to | |
93 | binaries in /usr, binaries that link to libraries in /usr or | |
94 | binaries that refer to data files in /usr. Since these | |
95 | breakages are not always directly visible systemd will warn | |
96 | about this, since this kind of file system setup is not really | |
97 | supported anymore by the basic set of Linux OS components. | |
