I've modified /etc/fstab system to use data=journal (even on root, which I thought wasn't supposed to work without a grub option!) and I can power-cycle the system and bring it up reliably afterwards. So I'm a little suspicious of this theory that /etc and others can be on the same partition as /boot in a non-ext3 file system. -- Moshe Yudkowsky * moshe@pobox.com * www.pobox.com/~moshe "Thanks to radio, TV, and the press we can now develop absurd misconceptions about peoples and governments we once hardly knew existed." -- Charles Fair, _From the Jaws of Victory_
