File 1006-sysv-restore-support-for-halt.local.patch of Package systemd-bsc1218671
From 0f93d44dc5892105b2cd04a3f3203c7633001480 Mon Sep 17 00:00:00 2001 From: Franck Bui <fbui@suse.com> Date: Wed, 30 Sep 2020 21:20:32 +0200 Subject: [PATCH 1006/1016] sysv: restore support for halt.local This patch basically reverts the following commits: - commit 44508946534eee032927c263b79464832656dd6e. "Drop support for /usr/sbin/halt.local" - commit c0d11245d2bdcf2a4333c3d49c973d83dfbe3791. "Drop no longer needed halt-local.service.in" The paths of the scripts in man/systemd-rc-local-generator.xml have been changed to match those used by SUSE. The use of halt.local is now deprecated and its usage is logged at notice level. --- docs/DISTRO_PORTING.md | 1 + man/custom-entities.ent.in | 1 + man/systemd-rc-local-generator.xml | 17 +++++++++++++--- meson.build | 2 ++ meson_options.txt | 2 ++ src/rc-local-generator/rc-local-generator.c | 8 ++++++++ units/halt-local.service.in | 22 +++++++++++++++++++++ units/meson.build | 4 ++++ 8 files changed, 54 insertions(+), 3 deletions(-) create mode 100644 units/halt-local.service.in diff --git a/docs/DISTRO_PORTING.md b/docs/DISTRO_PORTING.md index 93f36d0844..8a75f8dd1c 100644 --- a/docs/DISTRO_PORTING.md +++ b/docs/DISTRO_PORTING.md @@ -18,6 +18,7 @@ distribution: * `-Dsysvinit-path=` * `-Dsysvrcnd-path=` * `-Drc-local=` + * `-Dhalt-local=` * `-Dloadkeys-path=` * `-Dsetfont-path=` * `-Dtty-gid=` diff --git a/man/custom-entities.ent.in b/man/custom-entities.ent.in index e5aae04f4f..d7b6ff33a1 100644 --- a/man/custom-entities.ent.in +++ b/man/custom-entities.ent.in @@ -12,6 +12,7 @@ <!ENTITY KILL_USER_PROCESSES "{{ 'yes' if KILL_USER_PROCESSES else 'no' }}"> <!ENTITY DEBUGTTY "{{DEBUGTTY}}"> <!ENTITY RC_LOCAL_PATH "{{RC_LOCAL_PATH}}"> +<!ENTITY RC_LOCAL_SCRIPT_PATH_STOP "{{RC_LOCAL_SCRIPT_PATH_STOP}}"> <!ENTITY HIGH_RLIMIT_NOFILE "{{HIGH_RLIMIT_NOFILE}}"> <!ENTITY DEFAULT_DNSSEC_MODE "{{DEFAULT_DNSSEC_MODE_STR}}"> <!ENTITY DEFAULT_DNS_OVER_TLS_MODE "{{DEFAULT_DNS_OVER_TLS_MODE_STR}}"> diff --git a/man/systemd-rc-local-generator.xml b/man/systemd-rc-local-generator.xml index f0e38ead47..39c1fc9340 100644 --- a/man/systemd-rc-local-generator.xml +++ b/man/systemd-rc-local-generator.xml @@ -20,7 +20,7 @@ <refnamediv> <refname>systemd-rc-local-generator</refname> <refname>rc-local.service</refname> - <refpurpose>Compatibility generator and service to start <filename>&RC_LOCAL_PATH;</filename> during boot</refpurpose> + <refpurpose>Compatibility generator and service to start <filename>&RC_LOCAL_PATH;</filename> and <filename>&RC_LOCAL_SCRIPT_PATH_STOP;</filename> during boot and shutdown</refpurpose> </refnamediv> <refsynopsisdiv> @@ -53,11 +53,22 @@ Wants=network-online.target After=network-online.target </programlisting> - <para>Support for <filename>&RC_LOCAL_PATH;</filename> is provided for compatibility with specific System - V systems only.
