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