Just Usenet shit. The important part is when you run the program it opens up your default web browser, which in my case was perpetually firefox and idk why.
I've had mac rando on on fedora in the past and am running Graphene with it on by default, no breakages so far in about 2-2.5yr. Maybe my usecase doesn't need static MACs. The only issue is my home wifi says "a new device has been connected" every time I connect, but like, that's fine.
Good point on the hostname though, I usually use a specific name per device for my own sanity but maybe I should make them all generic "PC."
