(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I'm unable to reproduce this in Emacs 29.  I did:

touch file
ln -s file symfile

And then moved the file and the relative symlink with `R' in Dired, and
they were moved as expected (i.e., still relative).

Do you have a recipe for the problem you were seeing, or has this been
fixed in the years since it was reported?
