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 ore 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 the generator specification[1].
