If grub had been there it should have found it itself - but it wasn't so
I had to boot the CD.

I was able to do the install from the rescue mode boot, but only because
the /boot partition was all still intact and I only had to use the setup
command in grub.

There was only on drive at that point. It's syncing to a new mirror now.

Grub isn't so much the issue here as the difference in the rescue mode
boot. I'm used to being able to boot the CD, chroot into the existing
system and have pretty much normal access regardless of what was broken.
Now that the system /dev directory is basically empty, things don't work
when you have to mount the partitions manually. Is there a step to
set up devices so the chroot will work?
