# Purpose         : helper script for rpm scriptlets to remove a
#		    systemd unit.
#---------------------------------------------------------------

# Reload systemd configuration and try to restart units
# It has to be done in postun because package removal may delete
# some links and we need to inform systemd about it

pkg=$1				# name of the package
num=$2				# number of packages installed
shift 2				# systemd units

/bin/systemctl daemon-reload

    if [ -z "$DURING_INSTALL" ]; then
	    # New package may have removed some units so restart will
	    # fail for them; catch it.
	    # TODO find a way to pass parameters from current packages
	    # into script installed by previous version
