Not very much of Mini-OS -- Mirage has everything from the ring protocol
up (XenStore, NetBack/Front, BlkBack/Front, Console, etc are all in OCaml).
So event channels and start of day boot, mainly.

It is useful to have the C XenBus around for start-of-day logging though,
since the emergency console isn't much use on public cloud services.
