You're talking past each other.
Server people think that "hot-pluggable" means "I will tell the system
before it goes away". Normal users consider hot-pluggable to be "I can rip
the thing out by hand".
I'm with the normal users - I think the server guys are really talking
about "controlled shutdown and insert", not "hot-pluggable", but hey, the
fact is, there's two kinds.
Trying to enumerate three values with one bit is counterproductive.
So we should _not_ have one bit that says "hotpluggable", we should have
separate bits for "should survive a unexpected disconnect" (_real_
hotplug) and "can be disconnected with operator help" (server
"pseudo-hotplug").
USB devices are obviously supposed to be able to just be ripped out, ie
"unexpected", real hotplug. While FC etc tends to be "pseudo-hotplug".
