- No. BFFS 1.4 beta0 should be able to read your NetBSD-1.1
- FFS partitions as they are. The major changes in filesystem
- format from 4.3 BSD to 4.4 BSD involved write operations.
- Applications which just read the filesystem should remain
- compatible.

- The old (4.2/4.3 BSD) fast filesystem will show up as a 4.2
- under NetBSD-1.1. This is normal. What puzzles me is that
- if you did an installation from scratch with the NetBSD-1.1
- installation utilities, I'd think you should have a 4.4 BSD
- filesystem.
-
- I don't have complete confidence in what disklabel tells
- you the filesystem is. If it reads that information out of
- the disk label and not directly out of the filesystem, then
- there is a chance it's not telling you the truth. You may
- want to try using dumpfs and look at the format field it
- gives. Sorry, I don't have easy access to a NetBSD machine
- so I can't be more precise than this.
-
- If the filesystem is truly a 4.2 BSD filesystem (format < 2),
- then BFFS 1.31 should be able to write to it without
- corruption. Otherwise, I would recommend you get BFFS 1.4
- and not worry about reading.
