We should all be able to use it in a couple of months, in the
virtualisation world. The next release of VMware infrastructure is
going to support hot adding and removal of CPUs and memory to its

Too late, unfortunately. If HP has actually open-sourced AdvFS years
ago, when they announced the discontinuation of Tru64, things would
have been a lot better for us. But we've taken the hit now, and
copied all our data of it, so we don't care any more.

btrfs does indeed look good. I'll continue to mainly use XFS until
brfs gets here.

Er, in what way is Lustre not already 'Linuxised'? It's a standard
part of Debian Lenny, for example.
