I have not seen a quick reference or FAQ for this.

I frequently install gentoo and mess up.
Like when I go for the big test reboot it fails.
So then I go back and retrace steps, emerge something I forgot of, or look at such and such config file.
But first I need to re chroot.

I learned to do everything over ssh so I can copy and paste then post here. I am thinking maby this is not obvious to other noobs.

Is this the correct way to re boot re chroot?

Re booting with live cd on ppc:
Insert live cd and hold down c on keyboard to boot live cd.
G3 (insert other tips here)
Code:
modprobe bmac

Code:
dhcpcd

Code:
etc/init.d/sshd start

Open up a console and ssh over, Get the host key error with the new fingerprint and copy the fingerprint. Open
Code:
nano /root/.ssh/known_hosts
and paste the finger print there.
ssh in again type yes when it asks you if you approve.
(or let me know if their is a better way to do this)
from new ssh console
mount the partition hda(your root partition number here) you installed /root on in my case:
Code:
mount /dev/hda4 /mnt/gentoo

And if you made a seperate partition for /var or /usr or /home don't forget to mount them
Code:
mount /mnt/gentoo/your partition

Then
Code:
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
mount -o bind /sys /mnt/gentoo/sys
chroot /mnt/gentoo /bin/bash
/usr/sbin/env-update && source /etc/profile
code]
Code:
emerge --sync
(if I have not in last day)
to exit out of chroot and reboot
Code:
umount /mnt/gentoo/proc /mnt/gentoo/dev mnt/gentoo/sys

Code:
reboot


Any tips on making this correct or quicker?
