Sometime in the past few weeks, the ownership of /var/lock in Tumbleweed
changed from root:lock to root:root, breaking OpenHAB3's ability to create lock
files within that directory, unless it's given membership in the root group by
adding "SupplementaryGroups=root" in its systemd .service configuration (which
isn't the best security strategy).

This problem is very similar to bug #552095, which was reported nearly 14 years
ago and later resolved, although in a way that doesn't apply to my use case.

What this change deliberate? If not, could it be reversed? If it can't be
reversed, suggestions for a workaround would be appreciated.
