Hi Geza, hi everyone

Thanks. Praise indeed coming from a dev of your status:) I'd still like 
to see s3fs cope with file serving on the DC itself, as it's sooo much 
easier to setup.

What is wrong with Vbox? Is Xen any smaller or faster? Our DC has only 
2GB RAM. Running a VM on top of is already asking a lot of it. Also we 
have rpm's for host and guest out of the box on openSUSE. Can you take 
snapshots on Xen like on Vbox and roll back when you screw up?

On the NFS side of affairs I see it is impossible to create a group rw 
NFS4 share from a 0022 umask. The NFS devs seem unwilling or unable to 
do anything about it. Meanwhile the NFS3 Kerberos backport works well 
enough. Any ideas? A separate partition with a 0002 umask. Can I do that 
on the same disk?

Cheers,
Steve
