I'm _really_ interested in knowing how you reduced an AIX file system on the fly without blowing your feet off. The "official" way to reduce an AIX file system is a restore from a mksysb. I'd also like to see the journaled file system complete for FreeBSD, but I don't have the skill -- or the time to learn. I agree with Jordan. It's a far bigger job than it would seem. And, after all, I'm happy with what I've got -- so why tinker with it? -- Jay On Fri, 7 Nov 1997, Matthew D.
