We are forcing a change through the installer, which is where
the majority starts from.  We don't want to enforce a change
twice.

We can't really see if we installed or went through a factory
reset, so this is (was) the best of both worlds in conjunction
with the new installer feature.

While here, annotate that it is possible to leave it "empty".

This reverts commit 5eb2c986.
