• In opwnwrt:

opkg update && opkg install unfs3

edit the /etc/exports:

# cat /etc/exports 
/usr/portage    192.168.1.0/24(sync,no_root_squash,rw,no_subtree_check)

start these 2 services:

root@OpenWrt:~# /etc/init.d/portmap start
root@OpenWrt:~# /etc/init.d/unfs3  start

make these 2 services auto start at boot.

• In the client machine:

Add an entry into /etc/fstab for the share:

192.168.1.1:/usr/portage    /usr/portage    nfs    defaults,rw     0 0

Try to mount it automatically

/etc/init.d/nfsmount start

and add it to your default level

rc-update add nfsmount default

If you want to save some space, remove your local portage copy

umount /usr/portage 

rm -r /usr/portage/*

mount /usr/portage

Configuring eix

If you use eix for package searches, you'll need to change the method which eix uses to find out about packages. Edit /etc/eixrc and add the following line to the end of the file:

#cat /etc/eixrc
PORTDIR_CACHE_METHOD="parse"

Syncing Cache

Portage keeps a cache of package information relevent to the system which speeds up queries. This is normally updated during emerge --sync. Since your server is the only machine that runs emerge --sync, you will need to update the cache on the clients using:

emerge --metadata

If you want to have a cronjob for eix-sync create for example a file named /etc/cron.weekly/eix.cron

and put something like

#!/bin/sh

/usr/bin/eix-sync

in it.

In the client that don't run eix-sync, put

/usr/bin/eix-update

/usr/bin/emerge --metadata

in it.
