When root is on zfs, zpool.cache is supplied by bootloader as a module with type /boot/zfs/zpool.cache zfs.ko search for it by checking the filename /boot/zfs/zpool.cache and not the type.
>How-To-Repeat:
Load zpool.cache from a file other than /boot/zfs/zpool.cache 
>Fix:
Search for zpool.cache by the type and ignore the filename
