Hi All,

Generalizing the idea of "customizable meta packages" I would add also "the
possibility for the user to select a set of packages which he likes to have
installed, and those to be written in his /home partition". The idea is that
if the person upgrades to the next version of Ubuntu he should be able to
very easily restore the state of the previous installation. I know that this
can be achieved with a small script with several lines of apt-get, but it is
not always the most user-friendly format.
Perhaps a good idea will be from within synaptic the user to be able to
select some installed packages, mark them and make them a 'group' or
'metapackage'. Then this group to be saved where the user specifies. Later,
this 'group' could be loaded into synaptic and the package manager will
automatically downloa/install the needed packages.

Just an idea.
