The kdbuswreck

Actually, I never understood why tiny side cases like reboots need all that complexity.

Anybody noticed that we already have per-process namespaces ?
Oh, and we've got file permission flags since aeons.

Why not just giving things like the shutdown/reboot service their
own communication channel (ie. socket), which is only made available
to certain users or processes ? Either via perms or mounts, or by
some key authentication ?

Anybody had a look at Plan9 ?
It really could be so simple ...
