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

.SH "DESCRIPTION"

.PP
|
|
systemd\-debug\-generator
|
|
is a generator that reads the kernel command line and understands three options:
|
|
.PP
|
|
If the
|
|
\fBsystemd\&.mask=\fR
|
|
option is specified and followed by a unit name, this unit is masked for the runtime, similar to the effect of
|
|
\fBsystemctl\fR(1)\*(Aqs
|
|
\fBmask\fR
|
|
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\&.
|
|
.PP
|
|
If the
|
|
\fBsystemd\&.wants=\fR
|
|
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\&.
|
|
.PP
|
|
If the
|
|
\fBsystemd\&.debug\-shell\fR
|
|
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
|
|
\fBsystemctl\fR(1)\*(Aqs
|
|
\fBenable\fR
|
|
command\&.
|
|
