--root flag to apt-get (to install packages elsewhere) - possible?

[Tomasz Chmielewski <mangoo@wpkg.org>]

I have another Debian system mounted in /mnt/system2.

Now, I'd like to install some new packages there, or upgrade the whole 
/mnt/system2 system.

How can I do it with apt-get?


dpkg has "--root" option, but unfortunately it's missing from apt-get.

Any ideas?
