Well, yes. If it was declared explicitly in the propertyList ;)

I checked some other section configs and they all have an id (not always
named id) property, so the question is what to do about the FIXME comment:


Should we just remove the comment, because it's more consistent to other
section configs with the ID rather than without?

For the other one


we can just drop the auto-injection, because neither VZDump/JobBase.pm
nor Jobs/RealmSync.pm declare 'id' in their 'options', so the if
condition is never true AFAICT.

Okay, I see.
