генератор для включения оболочки отладки во время выполнения и маскирования определенных модулей при загрузке (Generator for enabling a runtime debug shell and masking specific units at boot)
Имя (Name)
systemd-debug-generator - Generator for enabling a runtime debug
shell and masking specific units at boot
Синопсис (Synopsis)
/usr/lib/systemd/system-generators/systemd-debug-generator
Описание (Description)
systemd-debug-generator is a generator that reads the kernel
command line and understands three options:
If the systemd.mask=
or rd.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. rd.systemd.mask=
is honored only by initial RAM disk
(initrd) while systemd.mask=
is honored only in the main system.
If the systemd.wants=
or rd.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.
rd.systemd.wants=
is honored only by initial RAM disk (initrd)
while systemd.wants=
is honored only in the main system.
If the systemd.debug_shell
or rd.systemd.debug_shell
option is
specified, the debug shell service "debug-shell.service" is
pulled into the boot transaction and a debug shell will be
spawned during early boot. By default, /dev/tty9 is used, but a
specific tty can also be set, either with or without the /dev/
prefix. Note that the shell may also be turned on persistently by
enabling it with systemctl(1)'s enable
command.
rd.systemd.debug_shell=
is honored only by initial RAM disk
(initrd) while systemd.debug_shell
is honored only in the main
system.
systemd-debug-generator implements systemd.generator(7).
