It is possible: http://www.gentoo.org/doc/en/altinstall.xml#doc_chap5 |
| 17 |

But not really recommended because if you do something wrong (wrong grub |
| 19 |
config, SSH misconfiguration, etc.) you'll need to go there and get |
| 20 |
physical access. |
| 21 |
|
| 22 |
Also, instead of installing a downloaded tarball, you can just clone the |
| 23 |
existing Gentoo installation into the new partition and boot from it. |
| 24 |
This usually means: |
| 25 |
|
| 26 |
'cp -a' your existing / to your target / (except /dev, /sys and /proc). |
| 27 |
If you mounted your target / as /root/target, you do: |
| 28 |
|
| 29 |
cp -a /usr /root/hd |
| 30 |
(repeat this for all directories in your current / *EXCEPT* /dev, /proc, |
| 31 |
/sys and /lost+found) |
| 32 |
|
| 33 |
mkdir /root/hd/dev |
| 34 |
mkdir /root/hd/proc |
| 35 |
mkdir /root/hd/sys |
| 36 |
mknod /root/hd/dev/console c 5 1 |
| 37 |
mknod /root/hd/null c 1 3 |
| 38 |
touch /root/hd/dev/.keep |
| 39 |
touch /root/hd/proc/.keep |
| 40 |
touch /root/hd/sys/.keep |
| 41 |
|
| 42 |
Now chroot into it: |
| 43 |
|
| 44 |
mount -t proc none /root/mnt/proc |
| 45 |
mount -o bind /dev /mnt/gentoo/dev |
| 46 |
chroot /root/hd /bin/bash |
| 47 |
|
| 48 |
Now edit /etc/fstab to use the new partitions, edit /boot/grub/grub.conf |
| 49 |
and reinstall grub: |
| 50 |
|
| 51 |
grub |
| 52 |
root (hd0,0) <-- sustitute with what you really have/want |
| 53 |
setup |
| 54 |
quit |
| 55 |
|
| 56 |
Now change your SSH config to allow for root login! (Or add a normal |
| 57 |
user if you don't want that.) In any case, check your SSH config. |
| 58 |
|
| 59 |
You're ready. Leave the chroot and unmount: |
| 60 |
|
| 61 |
exit |
| 62 |
umount /root/hd/dev |
| 63 |
umount /root/hd/proc |
| 64 |
|
| 65 |
If you've set up grub correctly while in the chroot, you can now reboot |
| 66 |
and the new system should come up. If not, I hope it's not a long drive |
| 67 |
or walk to get physical access :P |
