Below is the output from mount and a mirrordir script that runs from
cron.daily on a RH 7.0 box that I use to host a $-making email list.
hda1, 5, 6, 7, and 9 are partitions on the old primary hard disk which
probably only has another 1-2 years before a catastrophic failure. hdb1,
5, 6, 7, and 9 are partitions on an identical new hard drive. 

My goal is to make it as quick, simple, and cheap as possible to get
back up and running when the old drive bites the dust.

With my old system fully mirrored on the new drive this should be
possible, right? 

I assume that I can just pop a new drive back in the primary slot,
partition it properly, and mirrordir everything back to it from the
secondary and I'm up and running. 

It's not really going to be that simple is it?

What do I do with /proc? Should I mount the filesystem on a
/mirror/proc? What about automount, usbdevfs, and /dev/pts?

What else am I missing?
