When Dracut starts up, it needs to determine whether a pool will remain "hanging open" before the system shuts off. In such a case, then the code to clean up the pool (using the previous export -F work) must be invoked. Since Dracut has had a recent change that makes mount-zfs.sh simply not run when the root dataset is already mounted, we must use the cleanup hook to order Dracut to do shutdown cleanup. Important note: this code will not accomplish its stated goal until this bug is fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1385432 That bug impacts more than just ZFS. It impacts LUKS, dmraid, and unmount during poweroff. It is a Fedora-wide bug.
