|
|
|
=head1 SYNOPSIS
|
|
|
|
B<DEBIAN/preinst>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
A package can perform several pre-installation actions via maintainer
|
|
scripts, by including an executable I<preinst> file in its control
|
|
archive (i.e. I<DEBIAN/preinst> during package creation).
|
|
|
|
The script can be called in the following ways:
|
|
|
|
=over
|
|
|
|
=item I<new-preinst> B<install>
|
|
|
|
Before the package is installed.
|
|
|
|
=item I<new-preinst> B<install> I<old-version> I<new-version>
|
|
|
|
Before a removed package is upgraded.
|
|
|
|
The I<new-version> is passed only since dpkg 1.18.5.
|
|
|
|
=item I<new-preinst> B<upgrade> I<old-version> I<new-version>
|
|
|
|
Before the package is upgraded.
|
|
|
|
The I<new-version> is passed only since dpkg 1.18.5.
|
|
|
|
=item I<old-preinst> B<abort-upgrade> I<new-version>
|
|
|
|
