* Base scripts on the init scripts included with Debian GNU/Linux

  then take code from the already existing ones, trying to merge
  them into one.
  + NFS server service is just called 'nfs' in Redhat based system, and
    nfs-kernel-server on Debian GNU/Linux based.
  + Merge #2148 - Inform OpenRC that ZFS uses mtab.
  + Stop after umountfs
  + When stopping, don't check for LOCKDIR/zfs-mount - it won't be mounted,
    so the file won't exist making the script not run.
  + Add a configurable ZFS_INITRD_POST_MODPROBE_SLEEP used in the initrd to sleep after the modprobe.
  + The import function, do_import(), imports pools by name instead of '-a' [all].
    + Test all '/dev/disk/by-*' dirs for import. Include /dev as a last ditch attempt.
  + Fallback on importing the pool using the cache file (if it exists) if the
    'by-id' didn't work.
  + Add exceptions to pool imports.
* ZED script from the Debian GNU/Linux packages added.
