Modify the swap script so it starts before and stops after localmount. Also, on linux, this script should skip mounting swap on loopback. Add a swapfiles script which runs after localmount and is designed to activate additional swap space which could not be activated before localmount was run. This includes loopback swap on linux and swapfiles which are on local file systems that were not mounted when swap was activated initially. The start code does reactivate swap that is already active, but this is not an error condition.
