It's a message about an error:-)  It's also a bit of a pain as it keeps
coming back for every file under that mount point

Seems to work, thanks.  I've googled (and did find some of your
responses, but none on this variable.

It is autofs-5.1.0-10.fc21.x86_64 on linux kernel 3.18.7-200.fc21.x86_64.

glenn> ls -l /smb/.dir-locals.el
glenn> ls -ld /smb/.dir-locals.el

% ls -l /smb/.dir-locals.el
total 0
% ls -ld /smb/.dir-locals.el
dr-xr-xr-x 2 root root 0 Feb 24 08:10 /smb/.dir-locals.el

My map for /smb has a few named entries and then a wildcard entry, like:

* -fstype=autofs,-Dhost=&,-Duser=<cifs-username> file:/etc/<some-other-map>

and <some-other-map> has:

* 
-fstype=cifs,nocase,noserverino,credentials=<cred_file>,uid=${UID},gid=${GID},nounix
 ://${host}/&

so .dir-locals.el will be looked up as the hostname of a potential
windows machine that I may be able to mount, If the second wildcard, a
potential share exists, it will be mounted, so .dir-locals.el should
really be a directory (mount-point).  This would explain why emacs
thinks .dir-locals.el is a directory, because momentarily it is, until
the mount fails.
