a1 is to maintain and a2 is to upgrade, so the idea is to
always upgrade from a maintained state, that's why a2 first
calls a1. One could do a1 after a2 as well as
before, actually.

OK, thanks, fixed!

OK!

Well, none of this is automated necessarily, these commands
can be run by the user explicitely from the shell, it is how
I use them. I don't install a lot of things from the repos but
when I do the system get the implied sanity check by those
piles of commands.
Now they look like this:
a1 () {
sudo apt-get -qq check
sudo apt-get -qq update
sudo apt-get -qq autoremove
sudo aptitude -q=99 autoclean
apt -a list --upgradable
}
a2 () {
a1
sudo apt-get -qq upgrade
sudo apt-get dist-upgrade
}
