* category.create=pfrd
* moveonenospc=pfrd
* cache.files=off
* parallel-direct-writes=true

Just like functions you can now set a policy for moveonfreenospc. This
allows for more flexibility.
For backwards compatibility moveonfreenospc=true is converted to
moveonfreenospc=mfs.
minfreespace does apply which is slightly different from original behavior.
