Comment # 5 on bug 1183521 from Ignaz Forster

This bug had been fixed (a long time ago) in transactional-update 3.3.0: The
link to the RPM database is created as a relative link now.

The workdir issue is a bit more tricky, as we can't fix the old
transactional-update version. The bug was triggered when using an old
transactional-update version < 3.0, explicitly stating --no-selfupdate, on a
snapshot created with a transactional-update version >= 3.0; the *old*
transactional-update would fail to recognize the /etc overlay due to a changed
path of the workdir and not create a new overlay for this snapshot. The *new*
transactional-update will then fail to use that snapshot due to the missing
overlay for the snapshot.

Support for snapshots without corresponding overlay has been added meanwhile,
so the problem should at least fix itself.
