Yeah, Linux support has been laboriously reverse engineered.  And the
revisions are problematic.  Vista/Win7, for example, support
Honest-to-God symlinks as well as the hard links supported under
2K/XP.  I could actually use those in Windows, but symlinks alone
aren't sufficient to justify an upgrade.

It would indeed, but I'm not exactly holding my breath waiting.  I
have Win2K on the box FreeDOS is on, and found an open source extFS
driver that reads/writes the ext4 filesystems I use on the Linux
instances, and 2K has native FAT32 support, so I'm covered there.

I don't know of anyone doing so, but I haven't actually looked.  If
I'm in FreeDOS, my need to actually *read* an FS other than FAT is
small, and I can live without it.  If I need to get to the NTFS or
Ext4 slices, I'll boot into an OS that can.
