Just to expand that, I followed Neil's advice when setting my boxes up. |
| 20 |
I have an atom box as LAN server and an i5 workstation. I have a script |
| 21 |
which I run on the workstation to mount all the necessary directories on |
| 22 |
the chroot, including nfs-mounting the atom's /usr/portage/packages dir. |
| 23 |
Then I chroot into the 32-bit system as described in the installation |
| 24 |
handbook, env-update && . /etc/profile and away I go. |
| 25 |
|
| 26 |
Then, on the atom, I emerge -kuaDvN world to install from the packages |
| 27 |
I've just built. |
| 28 |
|
| 29 |
The only thing to be careful of is keeping the atom box and the chroot |
| 30 |
identical. /var/lib/portage/world and /etc/portage/ must be identical. |
| 31 |
Also /usr/src/linux/.config and /boot/ . |
| 32 |
|
| 33 |
Let me know if you'd like the mounting script. |
