But that's *exactly* what I have -- well, 5GB -- and which failed. 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.
