31cee6f6 | 32 | REQUIREMENTS: |
b7f44df5 LP |
33 | Linux kernel >= 2.6.39 |
34 | with devtmpfs | |
35 | with cgroups (but it's OK to disable all controllers) | |
36 | optional but strongly recommended: autofs4, ipv6 | |
ae446765 | 37 | libudev >= 172 |
c1c8ca81 | 38 | dbus >= 1.4.0 |
3ede835a LP |
39 | libcap |
40 | gtk+ >= 2.20 (optional) | |
41 | PAM >= 1.1.2 (optional) | |
42 | libcryptsetup (optional) | |
43 | libaudit (optional) | |
44 | libselinux (optional) | |
45 | tcpwrappers (optional) | |
46 | libnotify (optional) | |
47 | ||
48 | When you build from git you need the following additional dependencies: | |
49 | ||
c1c8ca81 | 50 | vala >= 0.10 |
3ede835a LP |
51 | docbook-xsl |
52 | xsltproc | |
53 | automake | |
54 | autoconf | |
55 | libtool | |
b62cfcea | 56 | gperf |
21bc923a | 57 | make, gcc, and similar tools |
3ede835a LP |
58 | |
59 | During runtime you need the following dependencies: | |
60 | ||
c1c8ca81 | 61 | util-linux > v2.18 (requires fsck -l, agetty -s) |
21bc923a | 62 | sulogin (from sysvinit-tools, optional but recommended) |
3ede835a LP |
63 | plymouth (optional) |
64 | dracut (optional) | |
21bc923a | 65 | |

66 | When systemd-hostnamed is used it is strongly recommended to |
67 | install nss-myhostname to ensure that in a world of | |
68 | dynamically changing hostnames the hostname stays resolveable | |
69 | under all circumstances. In fact, systemd-hostnamed will warn | |
70 | if nss-myhostname is not installed. Packagers are encouraged to | |
71 | add a dependency on nss-myhostname to the package that | |
72 | includes systemd-hostnamed. | |

74 | Note that D-Bus can link against libsystemd-login.so, which |
75 | results in a cyclic build dependency. To accomodate for this | |
76 | please build D-Bus without systemd first, then build systemd, | |
77 | then rebuild D-Bus with systemd support. | |

79 | WARNINGS: |
80 | systemd will warn you during boot if /etc/mtab is not a | |
81 | symlink to /proc/mounts. Please ensure that /etc/mtab is a | |
82 | proper symlink. | |
83 | ||
84 | systemd will warn you during boot if /usr is on a different | |
85 | file system than /. While in systemd itself very little will | |
ed1c99fc | 86 | break if /usr is on a separate partition many of its |
21bc923a LP |
87 | dependencies very likely will break sooner or later in one |
88 | form or another. For example udev rules tend to refer to | |
89 | binaries in /usr, binaries that link to libraries in /usr or | |
90 | binaries that refer to data files in /usr. Since these | |
91 | breakages are not always directly visible systemd will warn | |
92 | about this, since this kind of file system setup is not really | |
93 | supported anymore by the basic set of Linux OS components. | |
