Its worth noting that you can do the same thing with the native 9p
servers for linux (u9fs, spfs, or npfs).  Alternatively you could run
a AOE vblade server, or a p9p venti (although you'd still need a
solution for the fossil disk, but a ramdisk might be the best solution
here for speed).  It might be a nice project to bundle such an
environment with scripts for folks to use as an easy qemu/kvm start
environment with either Linux based file server or the
venti/ramdisk-fossil solution.
