This looks like a good start, a few comments below.

I suppose we should move this to a non-people location sooner rather
than later.

I think you also need to pass revision_{xen,qemuu,qemu,libvirt,ovmf} etc
and propagate them when you create the raisin config file instead of
hardcoding a bunch of stuff in the ts- script.

You should also call store_revision() for each git repo which was built
so that it is recorded in the flight metadata. You should do this for
_every_ git repo, not just ones which are explicitly set to a specific
revision (osstest cares for bisection purposes what was built even if it
cannot control that input tree).

Lastly you will (eventually) need to divide the output into one or more
component subtrees (e.g. ts-xen-build splits the hypervisor from the
tools in order to support 32-on-64 configs) and call built_stash_file on
them. Those then produce the outputs which other jobs can consume.

Ian.
