For upgrade testing purposes I wrote some scripts that essentially
does just that:
http://bazaar.launchpad.net/~auto-upgrade-testing-dev/auto-upgrade-testing/trunk/view/head:/share/scripts/install_all
Trying to install as many together as possible, first in the cache,
then for real.
When I worked on this ~2 years ago I found that from the ~20k package
it was possible to mark_install ~16k or so (the numbers are not
accurate, just from memory, be warned). When I actuallyed tried to
install this big package set I ran into scalability problems with the
parsing of the dpkg lists files. Unpacking was very slow and it looked
like the bottleneck was the .lists file parsing.
