NAME

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

SYNOPSIS

       /lib/systemd/system-generators/systemd-run-generator

DESCRIPTION

       systemd-run-generator is a generator that reads the kernel command line and understands
       three options:

       If the systemd.run= option is specified and followed by a command line, a unit named
       kernel-command-line.service is generated for it and booted into. The service has
       Type=oneshot set, and has SuccessAction=exit and FailureAction=exit configured by default,
       thus ensuring that the system is shut down as soon as the command completes. The exit
       status of the command line is propagated to the invoking container manager, if this
       applies (which might propagate this further, to the calling shell — e.g.  systemd-
       nspawn(7) does this). If this option is used multiple times the unit file will contain
       multiple ExecStart= lines, to execute all commands in order. The command is started as
       regular service, i.e. with DefaultDependencies= on.

       Use systemd.run_success_action= and systemd.run_failure_action= to tweak how to react to
       the process completing. In particular assigning "none" will leave the system running after
       the command completes. For further details on supported arguments, see systemd.unit(5).

       systemd-run-generator implements systemd.generator(7).

EXAMPLE

       Use a command like the following to add a user to the user database inside a container run
       with systemd-nspawn(7):

           # systemd-nspawn -D mycontainer -b systemd.run='"adduser test"'

       (Note the requirement for double quoting in the command line above. The first level of
       quoting ('') is processed and removed by the command shell used to invoke systemd-nspawn.
       The second level of quoting ("") is propagated to the kernel command line of the container
       and processed and removed by systemd-run-generator. Both together make sure both words of
       the specified command line adduser test end up in the generated unit file together and are
       neither split apart by the command shell nor by the generator.)
