Can someone tell me what steps are necessary to move the /

with this before, but cannot find the email. The oldest of
three drives on my system had my / partition, /dev/sdc1. One
day recently, that partition became inaccessable. After
quickly installing Ubuntu on a different drive, that root
partition eventually showed up again.
So I've been able to boot Gentoo again off the separate /boot
partition on /dev/sda1. I need to move that / partition. I
have several other partitions mounted off this one, mainly as
/usr and maybe /usr/local/, and some storage partitions
mounted to my home directory.
I copied the root (/) partition with the new partition at
/dev/sdb5 mounted as /newroot, using
# cp -ax / /newroot
I checked that /proc, /dev, and /sys are there, and empty. I
recall there are some other steps necessary. I changed
/etc/fstab, and the grub2 grub.cfg from ubuntu, the entry for
this kernel. The boot stalls at a certain point.
May I ask what steps are necessary to do this?
Thank you,

I have done this in the past. I usually boot the CD, make mount
points for old and new, then mount the old and new that I want to
copy. Then I do a cp -av /path/to/old /path/to/new/ and let it
copy. This can take quite a bit of time tho. It seems those
little bitty files take the longest. Maybe omitting the -v option
would help on that?
Once you get it copied over, edit your fstab file as needed on the
new side and install the bootloader as well. After that, it
usually just works.

P. S. Sorry for not including some fancy tarball stuff. ;-)
Well, as far as I know one would like to edit the bootloader
configuration as well, so as to reflect the new root directory.
Or has anyone written this before and I didn't notice? ;-)

If it needs to be then sure. I usually move things file wise with cp
then move things physically in the case as well. My OS is always on
hda. The grub config is on hda1 and grub bootloader is on the MBR of
hda as well. So, I don't have to edit grub on mine. I do boot once by
using the edit feature of grub, just to make sure before I move things
physically.
You do have to plan these things tho. Wouldn't hurt to write down on
paper where everything is and don't erase anything until you are sure
your ducks are in a row. Maybe even write notes on the drive with a
post it note.
