I have a second partition mounted on /loc, that is the reason for the multi-map autofs setup. With a separate mount on /loc, you won't see the errors with the old kernel. Fact is that my setup worked for a long time, and that it stopped working after the backport of commit 1064f874 to the ubuntu 4.4 kernel. -- Dick
