I wonder if it is possible to update a partition containing factory (10.3

It is possible with a simple chroot(1). I run SLED10-SP1 daily, but have
a separated partition with openSUSE-Factory, for development purposes.
Assuming that the openSUSE installation is on /dev/sda2, you can use
the following script (you'll probably have to tweak it to fit your environment):
#!/bin/bash
if ! grep -q /dev/sda2 /proc/mounts; then
mount /dev/sda2 /opensuse
fi
for part in proc sys dev; do
if ! grep -q /opensuse/$part /proc/mounts; then
mount --bind /$part /opensuse/$part
fi
done
cp -f /etc/resolv.conf /opensuse/etc/resolv.conf
chroot /opensuse
Here I assume I would insert the update procedure.
umount /opensuse/proc
umount /opensuse/sys
umount /opensuse/dev
umount /opensuse
I still have not tested this procedure on my factory partition, but I used
it as part of the recovery procedure of an old system, sucessfully, so I
must say thank you :-)
