I also feel that the "institutial knowledge" about the VM+VFS+UFS conglomerate seems to be going away. There were many attempts to port file systems to FreeBSD that have stopped dead once they've reached read-only phase, and recent problems with UFS looked really ugly (I don't even know if they are solved - I'm scared of filling up UFS drives right now :) ). My first production ZFS panicked the other day so ZFS is not yet the answer. (And yes, I know I'm complaining without suggesting solutions). --------------enig72D3E7F327F40266C670C4C1 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGnnwMldnAQVacBcgRAsKeAKDJ9hFk5HqQT33Y80SHGrqG8zzLfQCg4omY hf/RXcdEOs0jhLouP20ML1Y= =Tt5T -----END PGP SIGNATURE----- --------------enig72D3E7F327F40266C670C4C1--
