Gentoo 2.6.28.2

From Soekris Info Wiki

My soekris 4801 is an wlan access point and router for pppoe, installed on hardisk.

For updates i am using a chroot on a faster machine with rsync before and after updating. Another way for updates is using [distcc].

The Kernel configuration is here

My chroot environment is located on a 3GHz 32bit Intel machine at /soekris_chroot/.

Every time before updating i am using rsync to assign local updates to the chroot. Delete the "-n" switch if it looks good.

First part: Transfer local changes from soekris box to chroot environment. Attention: "--delete" is dangerous ;)

rsync --delete -Onalvz --numeric-id --exclude 'sys/' --exclude 'dev/' --exclude 'root/' \
--exclude 'proc/' --exclude 'usr/portage/' --exclude 'usr/src' --exclude \
'var/run/' --exclude 'var/log' --exclude 'tmp/' --exclude 'var/lib/init.d/' \
--exclude 'etc/chrony/chrony.drift' --exclude 'etc/adjtime' --exclude \
'etc/resolv.conf' root@soekris:/ /soekris_chroot/

Second part: Using this script to work in chroot, update everything and transfer updates to soekris.

#!/bin/bash
mount -o bind /dev /soekris_chroot/dev &&\
mount -t proc none /soekris_chroot/proc &&\
mount -o bind /dev/pts /soekris_chroot/dev/pts &&\
chroot /soekris_chroot || exit 1
umount /soekris_chroot/dev/pts
umount /soekris_chroot/dev
umount /soekris_chroot/proc
echo "rsync should be done next"
echo "rsync --delete  -Onalvz  --numeric-id --exclude 'sys/' --exclude 'dev/' --exclude \
'root/' --exclude 'proc/' --exclude 'usr/portage/' --exclude 'usr/src' \
--exclude 'var/run/' --exclude 'var/log' --exclude 'tmp/' --exclude \
'var/lib/init.d/' --exclude 'etc/chrony/chrony.drift' \
--exclude 'etc/adjtime' --exclude 'etc/resolv.conf' /soekris_chroot/ \
root@soekris:/"
