60 | docbook-xsl |
61 | xsltproc | |
62 | automake | |
63 | autoconf | |

3ede835a LP |
70 | |
71 | During runtime you need the following dependencies: | |

77 | When systemd-hostnamed is used it is strongly recommended to |
78 | install nss-myhostname to ensure that in a world of | |
79 | dynamically changing hostnames the hostname stays resolveable | |
80 | under all circumstances. In fact, systemd-hostnamed will warn | |
81 | if nss-myhostname is not installed. Packagers are encouraged to | |
82 | add a dependency on nss-myhostname to the package that | |
83 | includes systemd-hostnamed. | |
84 | ||
6705c2df | 85 | Note that D-Bus can link against libsystemd-login.so, which |
49f43d5f | 86 | results in a cyclic build dependency. To accommodate for this |
6705c2df LP |
87 | please build D-Bus without systemd first, then build systemd, |
88 | then rebuild D-Bus with systemd support. | |

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

109 | To run systemd under valgrind, compile with VALGRIND defined |
110 | (e.g. ./configure CPPFLAGS='... -DVALGRIND=1'). Otherwise, | |
111 | false positives will be triggered by code which violates | |
112 | some rules but is actually safe. | |
