=head1 SYNOPSIS

B<aa-post-stage0>

=head1 DESCRIPTION

B<aa-post-stage0>(1) is an B<execline> script meant to be used as handler for
B<aa-start>(1) return code in stage 0. In other words, it should be set as
I<REPODIR/.anopa/post-stage0>

It checks B<aa-start>(1) return code (given as argument) for bit 1 or 16, and if
at least one is set executes into an interactive shell (I<sh -i>).

Bit 1 being set means B<aa-start>(1) failed with a fatal error; Bit 16 means at
least one service marked essential failed.
