Um, no. This gives you new usr and var directories like so: |
| 27 |
|
| 28 |
/usr/usr/ |
| 29 |
/var/var |
| 30 |
|
| 31 |
You want: |
| 32 |
|
| 33 |
cp -a /mnt/gentoo/backup/var /mnt/gentoo/ |
| 34 |
cp -a /mnt/gentoo/backup/usr /mnt/gentoo/ |
| 35 |

It's correct, and it also highlights just what a PITA it is to manipulate |
| 40 |
traditional disk partitions. With lvm, this becomes a breeze. With ZFS (we |
| 41 |
might see it one day) this becomes invisible. |
