It seems to me like files created on nfs mounted directory don't have
the correct group id set:

% mkdir z
% chgrp othergroup z
% cd z
% touch foo
% ls -lgd foo

The file created on the nfs directory will not belong to othergroup
if othergroup is not the primary group if the creating process.

On a ufs partition, it works fine.

I don't know if this bug is present on 4.4BSD, but I guest it might.

On a different note:

Would it be possible to add the directory setgid flag to indicate the
semantics for group id on file creation like sunos, hpux and others?
