Yep. There is at least one bug i know of:
amd breaks when trying to stat()'ing an toplvl-mounted directory.
Common case: filename-expansion under bash/tcsh/zsh. The map-lookup
fails miserably due to uncorrect NFS-replies (NFS_lookup was called
with a NULL argument). unfortunately nobody was able to tell me whether
this is valid or not, so i weren't able to explore any further.

You can work around by simply not trying to make an expansion in the
toplvl-dir and, most notably, _stop updatedb to access an amd-mounted
dir_.

I'm running amd (my special patched upl102a) for approx 1 year now
without problems.

And yes, if you happen to know some hints on the NFS-stuff (even an
URL to the specs would be helpful), let me know.

Have fun

Hannes
