(As an exercise, consider a problem how to mount /etc when /etc/fstab isn't mounted.) However, having /var partition separate is quite common and I think is a recommended practice. And, of course, it must be a read/write partition. Now, a dumb question... Are you terminating your machine with halt or shutdown command ? Does your machine cleanly stop ? horio shoichi
