Come to think of it, I've migrated all of our IRIX filesystems to XFS
which is journaled like JFS. A FreeBSD XFS driver would certainly put a
smile on my face. I just mentioned EFS 'case I knew it existed amongst
the Linux folks. XFS has proved to be very stable under heavy load though
the procession of patches has made me wonder about how well they QA it.
I wish xfsdump had the v switch that Solaris' ufsdump has for verifying
a dump's integrity. Er, I'm drifting. Anyway, if you're interested in
developing an XFS driver for FreeBSD you have my moral support anyway!
