Excellent, thanks.

Yep.

I generally dislike the idea of having xen-specific daemons that aren't
useful to have on one's path under /usr/sbin/

Gerd said it was deprecated, and he works for a distro so it must be
true :-)

I'd go for /usr/lib/xen/bin

It would be good to do an audit of everything we install. I bet there's
random crap in tools/misc that aren't really user tools and shouldn't be
going in /usr/bin/

Interesting. I've a T42 laptop runing a CentOS4 dom0 that it happens
frequently on, but I haven't seen it on other machines..

Yep, hopefully.
