I followed the thread, but couldn't seem to see a conclusion at the end
of it. I also tested 2.4.0-test1-ac17 just now and it exhibits the same
issue.
Is the conclusion that I should be fixing XEmacs to follow the symlink
in userspace rather than relying on the kernel?
FWIW, there is /no/ support for doing this in XEmacs at present - which
would make linux-2.4 the only system where this was needed, so far as I
could see.
Thanks,
Daniel
