NAME

6       systemd-run-generator - Generator for invoking commands specified on
7       the kernel command line as system service
8

SYNOPSIS

10       /usr/lib/systemd/system-generators/systemd-run-generator
11

DESCRIPTION

13       systemd-run-generator is a generator that reads the kernel command line
14       and understands three options:
15
16       If the systemd.run= option is specified and followed by a command line,
17       a unit named kernel-command-line.service is generated for it and booted
18       into. The service has Type=oneshot set, and has SuccessAction=exit and
19       FailureAction=exit configured by default, thus ensuring that the system
20       is shut down as soon as the command completes. The exit status of the
21       command line is propagated to the invoking container manager, if this
22       applies (which might propagate this further, to the calling shell —
23       e.g.  systemd-nspawn(7) does this). If this option is used multiple
24       times the unit file will contain multiple ExecStart= lines, to execute
25       all commands in order. The command is started as regular service, i.e.
26       with DefaultDependencies= on.
27
28       Use systemd.run_success_action= and systemd.run_failure_action= to
29       tweak how to react to the process completing. In particular assigning
30       "none" will leave the system running after the command completes. For
31       further details on supported arguments, see systemd.unit(5).
32
33       systemd-run-generator implements systemd.generator(7).

EXAMPLE

36       Use a command like the following to add a user to the user database
37       inside a container run with systemd-nspawn(7):
38
39           # systemd-nspawn -D mycontainer -b systemd.run='"adduser test"'
40
41       (Note the requirement for double quoting in the command line above. The
42       first level of quoting ('') is processed and removed by the command
43       shell used to invoke systemd-nspawn. The second level of quoting ("")
44       is propagated to the kernel command line of the container and processed
45       and removed by systemd-run-generator. Both together make sure both
46       words of the specified command line adduser test end up in the
47       generated unit file together and are neither split apart by the command
48       shell nor by the generator.)
