Subject: [PATCH 1007/1007] 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.
