CCing the devel list -- all of these look useful to me.  Should we also
set the 'discard' option to enable TRIM on SSDs (or would this cause 
failures if the media doesn't support trimming?)

Do send a pull request on the existing changes and I'll merge/rebuild.

Incidentally, I added a Dockerfile to xen-arm-builder in order to make
it quicker to fetch a working tree.  The limits of containers start
showing up quite fast unfortunately, since the only way to mount a
loopback device is to use Docker in 'privileged mode', which none of the
public build services do.  Still, if anyone wants to play with it, you
just:

sudo docker.io pull avsm/xen-arm-builder
sudo docker.io run -t avsm/xen-arm-builder bash

Can't do much with it after that unless you're in a privileged local
container (if anyone gets that to work, drop a note on this thread).
