For some reason I post it here.
Defender was (and is) a very nice and handy tool. And it eases ad blocking and adds some privacy measures. All kudos to nodevel!

I could not (and still cannot) understand that systemd can be so bold to ‘support’ such situation causing full boot freezes.
It took me some efforts to grab what caused this but in the end found and solved it.
Furthermore I modified some code to handle as well nemo as defaultuser as valid GUI users.
New package is on openrepos
and code is on github
