systemd/0001-add-hdflush-for-reboot-or-hddown-for-poweroff.patch
Stephan Kulow 8f6010ffdf Accepting request 215598 from Base:System 
- Change patch 0001-add-hdflush-for-reboot-or-hddown-for-poweroff.patch
  to skip already by the kernel managed devices 

- fix timeout stopping user@.service (bnc#841544)
  * 0001-core-introduce-new-KillMode-mixed-which-sends-SIGTER.patch
  * 0002-service-allow-KillMode-mixed-in-conjunction-with-PAM.patch
  * 0003-core-make-sure-to-always-go-through-both-SIGTERM-and.patch

- Add patch 0001-upstream-systemctl-halt-reboot-error-handling.patch
  to be able to detect if the sysctl reboot() returns.
- Add patch 0001-add-hdflush-for-reboot-or-hddown-for-poweroff.patch
  A check for unmaintained disk like devices is added to be able to
  flush and maybe shut them down.  Also the missing sync() system
  call is added for the direct halt/reboot systemctl command. Then
  the system halt is used as fallback if poweroff fails for both
  the direct poweroff systemctl command as well as for the
  systemd-shutdown utility.

- Make systemd-mini build 

- Make requires bash-completion a recommends

- Add patch 1017-skip-native-unit-handling-if-sysv-already-handled.patch
  to avoid that enabled boot scripts will be handled as unit files
  by systemctl status command (bnc#818044)

- Drop patch 1017-enforce-sufficient-shutdown-warnings.patch
  as the original code behaves exactly as the shutdown code of
  the old SysVinit (bnc#750845)
- Rename support-powerfail-with-powerstatus.patch to

Raw Blame History

This seems to be a SUSE specific patch. Here we add the check for unmaintained
disk like devices to be able to flush and maybe shut them down. Also we add the
missing sync() system call for the direct halt/reboot systemctl command. Then we
use the system halt as gfallback if poweroff fails for both the direct poweroff
systemctl command as well as for the systemd-shutdown utility.
