I've been wondering about the status of XFS in (Free or other)BSD, know it's in ports and is usable in Linux. I think you can even run Linux on XFS instead of ext(2,3 or 4)fs, or ReiserFS, or btrfs. I remember Linux having read-only access, later also read-write, to HPFS, and I actually read HPFS partitions from Linux. That was long ago. Sometime during the single-digit days of April 2001, my OS/2 Warp 4 installation came apart when, following a crash where the file system was not cleanly dismounted, CHKDSK ran amok on reboot and trashed the entire hard disk, destroying a Linux installation as well. I was never able to boot any OS/2 again after that (trap 000c or 000d if it got that far), even from installation or other diskettes; there was no such thing as bootable CD back then, at least not for OS/2 Warp 4. Although OS/2 has continued on as eComStation (www.ecomstation.com), 32-bit i386 only, no 64-bit, eComStation has fallen far behind Linux and the BSDs. So one could say HPFS is antiquated, very few Linux or BSD users would have use for HPFS access; my last time was in April 2001. Tom
