NAME

       systemd-debug-generator - Generator for enabling a runtime debug shell and masking
       specific units at boot

SYNOPSIS

       /lib/systemd/system-generators/systemd-debug-generator

DESCRIPTION

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

       If the systemd.mask= option is specified and followed by a unit name, this unit is masked
       for the runtime, similar to the effect of systemctl(1)'s mask command. This is useful to
       boot with certain units removed from the initial boot transaction for debugging system
       startup. May be specified more than once.

       If the systemd.wants= option is specified and followed by a unit name, a start job for
       this unit is added to the initial transaction. This is useful to start one or more
       additional units at boot. May be specified more than once.

       If the systemd.debug_shell option is specified, the debug shell service
       "debug-shell.service" is pulled into the boot transaction. It will spawn a debug shell on
       tty9 during early system startup. Note that the shell may also be turned on persistently
       by enabling it with systemctl(1)'s enable command.

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