[clug] GFS - add some more abstraction [SEC=PERSONAL]

Hi Antti,

My take on GFS is that there is little to no need until you have
expensive (enterprise class?) hardware and needs.

If you don't have access to some form of reliable shared storage
system then the storage is probably still going to be your primary
failure point - NFS is pretty reliable once the underlying hardware
and OS are OK.

All the 'required services' probably start to make more sense once you
scale up - but I would agree with you that GFS is probably too much
pain for a small (presumably local) private network.
