I'm guessing between this thread and your "unmounting /" thread that
you're attempting to duplicate your root drive? I just tried this in
single user mode a few days ago with dd and it didn't work. The
resulting file system was "dirty" so I used 'fsck' to clean it. The
results were a complete unusable mess.
I tried another method described in my thread "Trouble Adding New Boot
Drive" but couldn't quite get it right. However I think I'm overlooking
something quite simple. You might like to look over the steps I took
and see if they make sense. Then if you get it to work, I'd be most
appreciative if you'd let me know what I missed. I'll send the message
to you if you want.
Good Luck!
