boot livecd/usb to a network connection, mount the gentoo partitions, |
| 12 |
enter the chroot, nominally: |
| 13 |
mount /dev/sdc3 /mnt/gentoo |
| 14 |
mount /dev/sdc1 /mnt/gentoo/boot |
| 15 |
cp -L /etc/resolv.conf /mnt/gentoo/etc/ |
| 16 |
mount -t proc none /mnt/gentoo/proc |
| 17 |
mount --rbind /sys /mnt/gentoo/sys |
| 18 |
mount --rbind /dev /mnt/gentoo/dev |
| 19 |
chroot /mnt/gentoo /bin/bash |
| 20 |
|
| 21 |
source /etc/profile |
| 22 |
export PS1="(chroot) $PS1" |
| 23 |
|
| 24 |
when done working in the chroot, make a graceful exit: |
| 25 |
exit |
| 26 |
cd |
| 27 |
umount -l /mnt/gentoo/dev{/shm,/pts,} |
| 28 |
umount -l /mnt/gentoo{/boot,/proc,sys,} |
| 29 |
reboot |
