It seems that dracut version 009 through 013 won't boot correctly when the zfs-dracut rpm package has been installed, but 'root=zfs' isn't used on the boot commandline, for example when the package has been installed on a system that _doesn't_ boot from a zfs filesystem. Signed-off-by: Jeremy Gill <jgill@parallax-innovations.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #377
