I have looked at that function but I found it more important to
encapsulate the real logic into the function (open coding it would be OK
if there was only one caller but we have 2 at the moment).
Well, wrapper for setting permissions can be created as well, though I
do not consider it really that important. You basically have a single
potential caller because parsing code sets only one thing at the time.

OK, I will make it char * instead.
