[olug] Announcing Fedora 13 (fwd)

[T. J. Brumfield]

I believe BTRFS is being marked as stable in the next kernel release. Fedora
is a community distro that lives close to the bleeding edge.

I wouldn't put anything super-critical on a BTRFS partition without
a backup, but then again, that is part of the appearl of BTRFS, that you can
go back to earlier snapshots of the same files. In fact, I believe with this
Fedora release, there is a package you can install to manage the snapshots
of files from within Nautilus.

If you plan to boot from a BTRFS partition, you will also need a GRUB patch.
