* Fix typo in rcS(5), proberly->properly (Closes: #484233).  Thanks to
  Julien Danjou for noticing.
* Fix typo in rcS(5), maually->manually (Closes: #493680).  Thanks to
  Xr for noticing.
* Modify runlevel detection code in invoke-rc.d to notice the
  difference between runlevels 0 and 6, and the boot runlevel, to
  make it possible to use invoke-rc.d during boot (Closes: 384509).
* Make sure to call restorecon after mounting tmpfs file systems, to
  set SELinux permissions (Closes: #493679).  Patch from Russell
  Coker.
* Move responsibility of stopping the splash screen process from
  individual init.d scripts to init.d/rc.  This make sure the
  progress calculation reflect reality, and that the splash screen
  is taken down in runlevel 1 (Closes: #431560) and that it stop
  before gdm and kdm (Closes: #422922, #489734).
* Skip error message from checkfs.sh when / is read-only.  Patch
  from Mirek Slugen (Closes: #492214).
