Remember the nosymlink option for automount? Well, that really meant, "don't do special handling for local mount points." We could introduce a similar option, though it would be hard to do so for only the server. >> Is there a map syntax that would work round this?

Well, autofs4 might still honor nosymlink. I'd have to look. -Jeff _______________________________________________ autofs mailing list autofs@linux.kernel.org http://linux.kernel.org/mailman/listinfo/autofs
