glad we have come to the same conclusion :)

I don't know why HostFS does that (->Standa). It might be another cool
feature...

no. Don't even ask what I have done there :-)

the way I understand it's that MiNT never knows it was a symlink.

right. It's working that way.

imagine some hot-plug stuff on the host (if it was creating symlinks).
Or just imagine someone being lazy to quit ARAnyM and reconfigure their
config file just to mount something they forgot to mount earlier (like a
flash disk or something). They just symlink another part of the hostfs
to the already mapped directory and they're done.

Again, not sure what has Standa in mind originally but see my A/B/C
choices in a mail to Alan. This still looks to me like the best of the
choices.

Anyway, we don't need to judge this feature - what we are trying to do
here is to find out why you can't see normal symlinks as symlinks,
right? Or can you see them now? You report both success and failure in
various mails so I am getting confused.

Remove the D:\ mapping if you don't like it. I added it to AFROS just to
show that ARAnyM can access the whole host filesystem, if needed.

I use the CVS version, naturally, but I have just disabled the "relative
symlink" patch I cooked at lunch time and the worst what happened was
that samantha.prg now points to /c/olga.app. Still a valid symlink,
though.
