Does anyone actually use the non-FHS compliant current default
of /var/xen/dump? Should we consider switching it to something more
standard? Perhaps having done so making it configurable wouldn't be
useful any more (although I'd be happy with it being so if desired).

FWIW Debian patches it to be /var/lib/xen/dump.

http://www.pathname.com/fhs/pub/fhs-2.3.html#VARCRASHSYSTEMCRASHDUMPS
also talks about /var/crash for system crash dumps, so it's not really a
perfect fit for vm dumps

So /var/lib/xen/dump seems to be best.

Ian.
