Package: libvirt-daemon-system
Version: 1.2.16-2
Severity: normal
Hi,
I noticed the following in postinst:
# Force virtlockd to reexec if enabled
if [ -d /run/systemd/system ] && systemctl status virtlockd.service
>/dev/null; then
systemctl reload virtlockd.service
fi
using systemctl status is bad, since it accesses the journal, which can
be quite costly.
If you only want to test if a service is active, you can use
systemctl is-active -q virtlockd.service, which is much more
lightweight.
The -q makes sure, you don't need to suppress stdout.
if [ -d /run/systemd/system ] && systemctl is-active -q virtlockd.service ; then
systemctl reload virtlockd.service
fi
Or even simpler for your use case
if [ -d /run/systemd/system ] ; then
systemctl reload-or-try-restart -q virtlockd.service
fi
I think reload-or-try-restart does already exactly what you want.
Cheers,
Michael
