This is a reasonable default there are cases when it makes sense to remap the slot id assigned by Linux using your own custom mapping. This commit adds support to zpool_layout to provide a custom slot mapping file. The file contains in the first column the Linux slot it and in the second column the custom slot mapping. By passing this map file with '-m map' to zpool_config the mapping will be applied when generating zdev.conf. Additionally, two sample mapping have been added which reflect different ways to map the slots in the dragon drawers.
