systemd/ulimit-support.patch
Andreas Jaeger bd156cfcf6 Accepting request 127017 from home:fcrozat:branches:Base:System 
- Add fix-dir-noatime-tmpfiles.patch: do not modify directory
  atime, which was preventing removing empty directories
  (bnc#751253, rh#810257).
- Add improve-restart-behaviour.patch: prevent deadlock during
  try-restart (bnc#743218).
- Add journal-bugfixes.patch: don't crash when rotating journal
  (bnc#768953) and prevent memleak at rotation time too.
- Add ulimit-support.patch: add support for system wide ulimit
  (bnc#744818).
- Add change-terminal.patch: use vt102 instead of vt100 as terminal
  for non-vc tty.
- Package various .wants directories, which were no longer packaged
  due to plymouth units being removed from systemd package.
- Fix buildrequires for manpages build.
