Using Gentoo CD to repair a broken system

[bus_drivr]

OK just my 2 cents,
To Fix things using the Gentoo install CD:
1) Boot from the CD
2) swapon /dev/hd??
3) mount /dev/hd?? /mnt/gentoo
4) mount -t proc proc /mnt/gentoo/proc
5) chroot /mnt/gentoo /bin/bash

I follow these lines to here, if i need to check my filesystem i can fsck from here and I can use my /etc/fstab to...

6) mount /boot

For me /usr is a different partition so
7) mount /usr

env-update
9)source /etc/profile
10) --fix whatever and reboot.

Actually to fsck you can do that from the LiveCD. If you don't have a hard copy of /etc/fstab cfdisk provides partition info.

I cannot edit my grub.conf as this FAQ says.
