Oops, I've overlooked this when it arrived. Sorry.
Same here, I can reproduce it. Surprisingly, it isn't a Tramp error,
because Tramp isn't involved :-)
The scenario described above results in the call
(make-symbolic-link "/sudo:root <at> server:/tmp/foo" "/tmp/bar" nil)
Tramp would be involved if either
- LINKNAME is a relative file name, and default-directory is remote, or
- LINKNAME is a remote file name.
LINKNAME is "/tmp/bar", and both conditions do not apply.
"/sudo:root <at> gandalf:/tmp/foo", the TARGET of the call, must only be a
string. Which syntax it is, or whether it is a valid file name, doesn't
matter.
So I fixed it in dired. If you try to create a symlink between two files
on different hosts, you'll get an error now.
Closing the bug.
Best regards, Michael.
