I just thought about another thing IFS would be very useful for: Helping to develop UFS journaling. Since the filesystem itself is very simple, and directories are not present, it should be pretty easy to journal, as the number of places that update the metadata is pretty low. This should be extremely useful when testing out the journal operations, once they have been implemented. -- Suleiman Souhlal | ssouhlal@vt.edu The FreeBSD Project | ssouhlal@FreeBSD.org
