Thank you Duncan.

This is exacly what I was looking for. I have already created a 32-bit chroot,
but wasn't very keen on the idea of issuing 10+ commands (mount -o bind...) to
start openoffice or firefox.

I was experimenting with "emerge -b" but sadly, everything gets installed into
/lib so it's not usable on the main root.

I will give the mentioned link a shoot and tell you how it goes.


Cheers,
B
