Keep an eye on expiration as well, make sure everything continues to expire correctly, often times autofs will continue to work ok even when it isn't quite expiring properly. > > After testing, I'll push this forward to Ubuntu, but I don't have high > hopes of it to be included in any update.

Ok, great, I'll keep testing myself and post it on LKML provided we don't have any further problems. > > If I understand this correctly, would this be the fix needed for the > 'nested mounts with loop'-problem Mathias Koenig sees, as the problem > seems to be quite a similar one as ours ...

I'll be committing something very similar to the autofs repo and putting the patch on kernel.org soonish.
