Well of course you'd need to compile libxenctrl (and libxenstore) for that
environment too.

Of course! I'd forgotten about the special shell prompt hack. Well that
seems like a much easier way to do it.

Yes, it would be nice for more general cases, but that of course means
controlling the guest environment, and that would mean more interaction with
distro-specific aspects than I personally would like to take on at the moment.
It's not scary when we're doing it for xm-test, because we do control that
environment, but doing it for general guests is more fiddly. However, I'm
sure somebody somewhere will want to know when the guest is actually booted,
as opposed to merely started, and writing to xenstore seems like a good way to
go about it.
I'd still go with the shell prompt hack though.
Ewan.
