230 | configuration of the invoked unit, as well as access to runtime and exit code/status information of | |
231 | the invoked shell process. In particular, use <command>systemd-run</command>'s | |
232 | <option>--wait</option> switch to propagate exit status information of the invoked process. Use | |
233 | <command>systemd-run</command>'s <option>--pty</option> switch to acquire an interactive shell, | |
234 | similarly to <command>machinectl shell</command>. In general, <command>systemd-run</command> is | |
235 | preferable for scripting purposes. However, note that <command>systemd-run</command> might require | |
ec07c3c8 AK |
236 | higher privileges than <command>machinectl shell</command>.</para> |

968 | ||
969 | <para>The <command>machinectl</command> tool operates on machines | |
b938cb90 | 970 | and images whose names must be chosen following strict |
38b38500 | 971 | rules. Machine names must be suitable for use as hostnames |
91913f58 LP |
972 | following a conservative subset of DNS and UNIX/Linux |
973 | semantics. Specifically, they must consist of one or more | |
974 | non-empty label strings, separated by dots. No leading or trailing | |
975 | dots are allowed. No sequences of multiple dots are allowed. The | |
a8eaaee7 | 976 | label strings may only consist of alphanumeric characters as well |
91913f58 LP |
977 | as the dash and underscore. The maximum length of a machine name |
978 | is 64 characters.</para> | |
979 | ||
980 | <para>A special machine with the name <literal>.host</literal> | |
981 | refers to the running host system itself. This is useful for execution | |
a8eaaee7 | 982 | operations or inspecting the host system as well. Note that |
91913f58 LP |
983 | <command>machinectl list</command> will not show this special |
984 | machine unless the <option>--all</option> switch is specified.</para> | |
985 | ||
a8eaaee7 | 986 | <para>Requirements on image names are less strict, however, they must be |
91913f58 LP |
987 | valid UTF-8, must be suitable as file names (hence not be the |
988 | single or double dot, and not include a slash), and may not | |
989 | contain control characters. Since many operations search for an | |
b938cb90 | 990 | image by the name of a requested machine, it is recommended to name |
91913f58 LP |
991 | images in the same strict fashion as machines.</para> |
992 | ||
993 | <para>A special image with the name <literal>.host</literal> | |
a8eaaee7 | 994 | refers to the image of the running host system. It hence |

996 | name described above. Note that <command>machinectl | |
