NAME

6       systemd-debug-generator - Generator for enabling a runtime debug shell
7       and masking specific units at boot
8

SYNOPSIS

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

DESCRIPTION

13       systemd-debug-generator is a generator that reads the kernel command
14       line and understands three options:
15
16       If the systemd.mask= option is specified and followed by a unit name,
17       this unit is masked for the runtime, similar to the effect of
18       systemctl(1)'s mask command. This is useful to boot with certain units
19       removed from the initial boot transaction for debugging system startup.
20       May be specified more than once.
21
22       If the systemd.wants= option is specified and followed by a unit name,
23       a start job for this unit is added to the initial transaction. This is
24       useful to start one or more additional units at boot. May be specified
25       more than once.
26
27       If the systemd.debug_shell option is specified, the debug shell service
28       "debug-shell.service" is pulled into the boot transaction. It will
29       spawn a debug shell on tty9 during early system startup. Note that the
30       shell may also be turned on persistently by enabling it with
31       systemctl(1)'s enable command.
32
33       systemd-debug-generator implements systemd.generator(7).
