Wow, evidence that someone else out there has used dosemu!  Thanks for

Sadly, I tried all possible choices of \ and / for the path
delimieters, and the error was the same each time.

Yup, I can see my windows partition if I cd /mnt/windows in linux just
fine.  Also, as far as I can tell, there's no reason the target of
lredir needs to be a mounted dos partition -- you ought to be able to
mount /tmp just as easily -- but I couldn't do that either.

I *think* that when you use lredir to get dosemu to see your
linux-mounted dos file system, each fs access involves linux reading
the dos fs, doing some translation to make it look linux-like, then
lredir reading that and doing its own translation to make it look
dos-like again!

But since I can't get lredir to see anything at all, I'm not one to talk...
