31cee6f6 | 36 | REQUIREMENTS: |
b7f44df5 LP |
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 | |
c1c8ca81 | 41 | dbus >= 1.4.0 |
3ede835a | 42 | libcap |
3ede835a LP |
43 | PAM >= 1.1.2 (optional) |
44 | libcryptsetup (optional) | |
45 | libaudit (optional) | |
46 | libselinux (optional) | |
47 | tcpwrappers (optional) | |

49 | When you build from git you need the following additional dependencies: | |
50 | ||
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 | 63 | dracut (optional) |
21bc923a | 64 | |

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

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

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