NAME
dh_systemd_start - start/stop/restart systemd unit files
SYNOPSIS
dh_systemd_start [debhelper options] [--restart-after-upgrade] [--no-restart-on-upgrade] [unit file ...]
DESCRIPTION
dh_systemd_start is a debhelper program that is responsible for starting/stopping or restarting systemd
unit files in case no corresponding sysv init script is available.
As with dh_installinit, the unit file is stopped before upgrades and started afterwards (unless
--restart-after-upgrade is specified, in which case it will only be restarted after the upgrade). This
logic is not used when there is a corresponding SysV init script because invoke-rc.d performs the
stop/start/restart in that case.
OPTIONS
--restart-after-upgrade
Do not stop the unit file until after the package upgrade has been completed. This is different than
the default behavior, which stops the unit file in the prerm and starts it again in the postinst
maintscript.
This can be useful for daemons that should not have a possibly long downtime during upgrade. But you
should make sure that the daemon will not get confused by the package being upgraded while it's
running before using this option.
-r, --no-restart-on-upgrade
Do not stop service on upgrade.
--no-start
Do not start the unit file after upgrades and after initial installation (the latter is only relevant
for services without a corresponding init script).
NOTES
Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command
(with the same arguments). Otherwise, it may cause multiple instances of the same text to be added to
maintainer scripts.
Note that dh_systemd_start should be run after dh_installinit so that it can detect corresponding SysV
init scripts. The default sequence in dh does the right thing, this note is only relevant when you are
calling dh_systemd_start manually.
