We should have this working in the near term. The aim is to have another
api call to Duffy that allows you to submit your own kickstart, and wait
for the machine to redeploy ( it would be 4 to 7 minutes depending on
activity ).

The backing disks however, are limited - so you could potentially do a
large vg, with only a small chunk allocated, but you wont be able to
actually do multiple block devices ( yet ).

The option of having iscsi blocks available for folks to consume has
been thrashed out as well, its on the cards, but I dont think we are
going to be in a position to get that setup in the next 4 to 8 week
period ( basically, this becomes an option once we are all consolidated
into the new hosting facility, but have no confirmed date for that yet
other than - in the next few months ).

perhaps ? use that to setup some disks... ideally, to not do any
performance numbers though :)
