EFS 1.9 bug: Guardian - empty directory - can't grok filenames

To whom it may concern:


The Guardian stuff in 1.9 is excellent. Just one problem: If I try to
write a file or dired copy a file to a location on tandem that doesn't
exist, $system.regex in this case, you get "Can't grok Guardian
filenames" but under Guardian, a subvolume only exists if a file
exists using that subvolume. So when the first file is written to
$system.regex, $system.regex then exists. If you do a find-file on
$system.regex you get the same message, instead of an empty dired
listing. Is it possible to check when $volume.subvol doesn't exist and
return an empty directory instead of giving the message
