Yes. But I suppose, the symlink inside of the symlinked directory are a
problem. texdoc starts at /u/s/t-t/doc and may expect it is a directory.
When it checks if
/u/s/t-t/doc/latex/amsmath/../../../texlive-latex-base/latex/amsmath/amsldoc.pdf.gz
exists, it fails for the known reason.

I don't know how texdoc work. It's only a conjecture.

But, while we talk about how texdoc work, how does it work? Does it use
the ls-R files? The funny at me is that texdoc -s is much faster than
texdoc after the first run. The first run takes very long, because the
cache must get filled. But if the directory listing is in the cache it is
faster than texdoc -l.

Bye, Jörg.
