=head1 NAME
dh_installmodules - register modules with modutils
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
use File::Find;
=head1 SYNOPSIS
B<dh_installmodules> [S<I<debhelper options>>] [B<-n>]
=head1 DESCRIPTION
dh_installmodules is a debhelper program that is responsible for
registering kernel modules with modutils.
Files named debian/package.modules will be installed as
etc/modutils/package in the package build directory.
Then postinst and postrm commands are automatically generated to register
the modules when the package is installed. See L<dh_installdeb(1)> for an
explanation of how this works. Note that this will be done for any
package this program acts on which has either the above-mentioned file, or
has .o files in /lib/modules.
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify postinst/postrm scripts.
=back
=head1 NOTES
Note that this command is not idempotent. "dh_clean -k" should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.

# Returns true if there are any .o files in the passed directory.

return @results > 0;

doit("install","-d","$tmp/etc/modutils");
}
doit("install","-m","0644",$file,"$tmp/etc/modutils/$package");
}
if (! $dh{NOSCRIPTS} &&
($file || find_kernel_modules("$tmp/lib/modules"))) {
autoscript($package,"postinst","postinst-modules","s/#PACKAGE#/$package/");
autoscript($package,"postrm","postrm-modules","s/#PACKAGE#/$package/");
}
}
