Hi list,
I have been using autofs V3 for some years now and it always worked fine. It
even worked on diskless clients witch had the root fs
mounted ro, you just had to create the mount directory beforehand.
With V4, this does not seem to work anymore. Trying to start automount results
in: (Sorry for the long lines :-))

This is the original Debian sarge kernel.
Is there any way to make this work?
Thanks for any help, and sorry again for the long lines,
but i thought the strace output might be easier to read.
