RFC for VKERNEL 'external' shutdown
I'll probably start working on a little patch soon to enable 'clean'
VKERNEL shutdown from the host system via some simple mechanism such as
a signal handler.
Before I dig too deeply, a couple questions:
1) does this sound useful?
2) any 'gotchas' I should know about ?
(e.g. VMSPACE / strange signal interaction)
3) thoughts on best implementation?
I'm thinking the easiest and most 'real-system-like' would be to
pass the same signals mentioned in init(8) directly to the in-VKERNEL
init, which would "just work" (TM) & make things most consistant
with a 'real system', although making TERM do a full shutdown
might better suited to the vkernel environment (so all the
vkernel systems don't need to fsck on boot when the host does
a shutdown and inadvertently kills them)
Thanks in advance,
