Run the main urpm loop:

=item * split the work in smaller transactions
=item * for each transaction:
=over
=item * prepare the transaction
=item * download packages needed for this small transaction
=item * verify packages
=item * split package that should be installed instead of upgraded,
=item * install source package only (whatever the user is root or not, but use rpm for that)
=item * install/remove other packages
=back
=item * migrate the chrooted rpmdb if needed
=item * display the final success/error message(s)
=back
