The B<essential> set plus apt. This variant uses the fact that B<apt> treats
itself as essential and thus running C<apt-get dist-upgrade> without any
packages installed will install the B<essential> set plus B<apt>. If you just
want B<essential> and B<apt>, then this variant is faster than using the
B<essential> variant and adding B<apt> via C<--include> because all packages
get installed at once. The downside of this variant is, that if it should
happen that an B<essential> package is not installable, then it will just get
ignored without throwing an error.
