It'd be nice if Linux had a generic way of communicating a reboot

How about simply reusing whatever signal is sent to init
when ctrl-alt-del is pressed on PCs ?
SIGINT
That's not a good idea though, if somebody put nothing in the ctrlaltdel
action, then it's not going to do anything.
Aren't we trying to something a bit unnatural here? Clearly, shutting
down is something best done from userspace.
Maybe it's time to start thinking about domU tools for Xen userspace?
If the XenStore API can be accessible via userspace we could easily
write some patches (or special daemons) that could do this sort of
stuff. Might be particularily useful if we want to provide more
sophisticated stuff in the future.
Not something for Xen 3.0 but might be interesting for 3.1.x.
Thoughts? Am I crazy? :-)
