=head1 NAME
dh_installsysusers - install and integrates systemd sysusers files
=cut
use strict;
use warnings;
use Debian::Debhelper::Dh_Lib;
our $VERSION = DH_BUILTIN_VERSION;
=head1 SYNOPSIS
B<dh_installsysusers> [S<I<debhelper options>>]
=head1 DESCRIPTION
B<dh_installsysusers> is a debhelper program that is responsible for
installing package maintainer supplied systemd sysusers files.
It also finds the systemd sysusers files installed in a package and
generates relevant integration snippets for enabling the users on
installation. These snippets are added to the package by
L<dh_installdeb(1)>.
=head1 FILES
=over 4
=item debian/I<package>.sysusers
If the file exist, it will be installed as
F<< /usr/lib/sysusers.d/I<package>.conf >>.
=back
=head1 OPTIONS
=over 4
=item B<--name=>I<name>
When this parameter is used, B<dh_installsysusers> looks for and
installs files named debian/I<package>.I<name>.sysusers instead
of the usual debian/I<package>.sysusers.
Furthermore, the file is installed as F<< /usr/lib/sysusers.d/I<name>.conf >>
rather than F<< /usr/lib/sysusers.d/I<package>.conf >>.
=back
=head1 NOTES
This command is not idempotent. L<dh_prep(1)> should be called between
invocations of this command (with the same arguments). Otherwise, it
may cause multiple instances of the same text to be added to
maintainer scripts.
