#!/usr/bin/perl =head1 NAME dh_installinitramfs - install initramfs hooks and setup maintscripts =cut use strict; use warnings; use Debian::Debhelper::Dh_Lib; our $VERSION = DH_BUILTIN_VERSION; =head1 SYNOPSIS B<dh_installinitramfs> [S<B<debhelper options>>] [B<-n>] =head1 DESCRIPTION B<dh_installinitramfs> is a debhelper program that is responsible for installing Debian package provided initramfs hooks. If B<dh_installinitramfs> installs or detects one or more initramfs hooks in the package, then it also automatically generates the noawait trigger B<update-initframfs> command needed to interface with the Debian initramfs system. This trigger is inserted into the packaging by L<dh_installdeb(1)>. =head1 FILES =over 4 =item debian/I<package>.initramfs-hook Assumed to be an initramfs hook that will be installed into F<< usr/share/initramfs-tools/hooks/I<package> >> in the package build directory. See B<HOOK SCRIPTS> in L<initramfs-tools(8)> for more information about initramfs hooks. =back =head1 OPTIONS =over 4 =item B<-n>, B<--no-scripts> Do not add the B<update-initramfs> trigger even if it seems like the package might need it. The option is called B<--no-scripts> for historical reasons as B<dh_installinitramfs> would previously generate maintainer scripts that called B<update-initramfs -u>. Use this option, if you need to interface with the B<update-initramfs> system that is not satisfied by the noawait trigger (e.g. because you need the extra guarantees and head-aches of a await trigger). =back =head1 NOTES Note that this command is not idempotent. L<dh_prep(1)> should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to triggers file. =cut init(); # PROMISE: DH NOOP WITHOUT initramfs-hook tmp(usr/share/initramfs-tools/hooks) cli-options() foreach my $package (@{$dh{DOPACKAGES}}) { my $tmp = tmpdir($package); my $hook_script = pkgfile($package, 'initramfs-hook'); my $has_hooks; my $hook_dir = "${tmp}/usr/share/initramfs-tools/hooks"; if ($hook_script ne '') { install_dir($hook_dir); install_prog($hook_script, "${hook_dir}/${package}"); $has_hooks = 1; } elsif (-d $hook_dir and not is_empty_dir($hook_dir)) { $has_hooks = 1; } if ($has_hooks && ! $dh{NOSCRIPTS}) { autotrigger($package, 'activate-noawait', 'update-initramfs'); } } =head1 SEE ALSO L<debhelper(7)> L<update-initramfs(8)> L<initramfs-tools(8)> This program is a part of debhelper. =head1 AUTHOR Niels Thykier <niels@thykier.net> =cut
