This way I can't work on its support...
Tell me more about umsdos, which commands are required to set it
up on a second console? I don't have dos flying around so I'll
have to do everything under Linux. Assume I have a blank dos
partition (mkdosfs). What are the next steps.

Until now I thought that if umsdos was used and \LINUX\ should be used
as umsdos path, it gets mapped transparently and you won't have to fiddle
with \LINUX\ unless you enter the /orig path or something like that.

I haven't installed Debian on umsdos yet. I installed it into a
file /dev/hdb1:/file, 300MB large.

Are you *sure* that you did you the umsdos driver and not the msdos
driver? What you explain looks like dos-fat and not umsdos.
Speaking of umssync: Is that program in the root fs? I don't think
so...

I've spent four days on fixing this, no luck. You're invited to
develop the real fix. We went that far that symbols are in libraries
where we didn't expect them... Doesn't help since the symbol is not
on the rootfs.

You can *always* switch to the 2nd console, mount the floppy, copy
a file from there to /target/sbin and run it.

umsdos is not very common these days...

Need more input. At the moment I'm willing to spend some time on it.
