systemd.socket,
systemd.mount,
systemd.swapDescriptionUnit configuration files for services, sockets,
mount points and swap devices share a subset of
configuration options which define the process killing
parameters of spawned processes.This man page lists the configuration options
shared by these four unit types. See
systemd.unit5
for the common options of all unit configuration
files, and
systemd.service5,
systemd.socket5,
systemd.swap5
and
systemd.mount5
for more information on the specific unit
configuration files. The execution specific
configuration options are configured in the [Service],
[Socket], [Mount] resp. [Swap] section, depending on the unit
type.OptionsKillMode=Specifies how
processes of this service shall be
killed. One of

.If set to
all
remaining processes in the control
group of this unit will be terminated
on unit stop (for services: after the
stop command is executed, as
configured with
ExecStop=). If set
to only the
main process itself is killed. If set
to no process is
killed. In this case only the stop
command will be executed on unit
stop, but no process be killed
otherwise. Processes remaining alive
after stop are left in their control
group and the control group continues
to exist after stop unless it is
empty. Defaults to
.Processes will first be
terminated via SIGTERM (unless the
signal to send is changed via
KillSignal=). If
then after a delay (configured via the
TimeoutSec= option)
processes still remain, the
termination request is repeated with
the SIGKILL signal (unless this is
disabled via the
SendSIGKILL=
option). See
kill2
for more
information.KillSignal=Specifies which signal
to use when killing a
service. Defaults to SIGTERM.
SendSIGKILL=Specifies whether to
send SIGKILL to remaining processes
after a timeout, if the normal
shutdown procedure left processes of
the service around. Takes a boolean
value. Defaults to "yes".
