Re: rare but repeating system crash in C7

Erm ... the noauto should be part of the options column, so append it to the previous option (and of course delimit with a ",").

I see that the '.automount' was not generated ... Maybe it's related to the noauto issue.

By the way , "mount -a" should complain if fstab is not OK.

the fstab statement I put in my last posting was a copy/paste from /etc/fstab, so it should be correct as shown. I don't see a comma before noauto.
