Make use of Dracut's ability to restore the initramfs on shutdown and
pivot to it, allowing for a clean unmount and export of the ZFS root.
No need to force-import on every reboot anymore.

The standard dracut directory has moved from /usr/share/dracut to
/usr/lib/dracut. To ensure the dracut modules get installed in
the correct location provide a --with-dracutdir configure option
to set the path.
The default install location has been updated to /usr/lib/dracut
which is used by more current versions of Fedora. However, this
default is overriden by the RPM packaging for consistency.

This ensures that module-setup.sh script will always be able to
install the required dracut components regardless of how the zfs
package was configured.

This rule does not need to be dracut specific. Automatically loading
the zfs module stack when a zfs device is detected is usually desirable.
My only concern is that this might cause trouble for large pools where
we don't want to automatically import the pool until all the disks are
available. However, we'll cross that bridge when we come to it.

Update Dracut module for Dracut-010 and fix race conditions that
caused boot to fail on MP systems. Add support for zfs_force flag
and parsing of spl_hostid from kernel command line.

The zfs dracut modules should be installed under the --datadir
not --datarootdir path. This was just an oversight in the
original Makefile.am.
After this change %{_datadir} can now be set safely in the
zfs.spec file. The 'make install' location is now consistent
with the location expected by the spec file.
To simplify the process of using zfs as your root filesystem a
zfs-drucat sub-package has been added. This sub-package adds a zfs
dracut module which allows your initramfs to be rebuilt with zfs
support. The process for doing this is still complicated but there
is clearly interest from the community about getting this working
well and documented. This should help lay some of the groundwork.
Longer term these changes should be pushed in the upstream dracut
package. Once that occurs this subpackage will no longer be
required for new systems, however we may want to conditionally
build this package in the future for systems running older
dracut versions.
