Eh yes.

But ehm... the problem here is that prefix itself has nothing to do with
dropping privileges.  We just drop privileges, because there is no
reason to have them in a prefix (except for things like ping or
traceroute maybe).  Hence, prefix has nothing to do with users and
permissions here.  It is a side-effect which is very much desirable (to
me) but actually getting in the way now.

I think this is just manual "userwork" of getting it right.  I don't
believe common sense or global variables can help here.  It's too much
of a border case here.
