I think we don't really need them. We only need 3 operating "modes" in 90% of the cases: normal, administrator, guest. And after that various per-application permissions a la Android or iOS.
We don't need multi-users systems.
- bluejekyll 11y agoI think multi-user in this context is more about authorization of operations. It's correct that we don't need users/groups for this today, there are equally good things in cgroups and pam, but it's a simpler abstraction in many cases. I think your mostly correct, but in most cases I would prefer individual authorization rules, like apparmor. There's always cases when you don't want to escalate the entire app to root level, but need something more than what's a normal mode.
