Ah ha !

So the cachefile property needs to be a specific filename or that script
will have no clue.

Take a look :

titan# zpool get cachefile leaf proteus t0
NAME     PROPERTY   VALUE      SOURCE
leaf     cachefile  -          default
proteus  cachefile  -          default
t0       cachefile  -          default
titan#

Those files exist and they seem to be either from early this year or 
today :

titan# ls -l  /etc/zfs/zpool.cache /boot/zfs/zpool.cache
-rw-r--r--  1 root wheel 1424 Jan 16  2024 /boot/zfs/zpool.cache
-rw-r--r--  1 root wheel 4960 Nov 28 13:03 /etc/zfs/zpool.cache
titan#
titan# date -u
Thu Nov 28 14:13:51 UTC 2024
titan#
titan# uptime
  2:13PM  up  2:19, 1 user, load averages: 0.00, 0.00, 0.00
titan#

titan# zpool set cachefile="/etc/zfs/zpool.cache" leaf
titan# zpool set cachefile="/etc/zfs/zpool.cache" proteus
titan# zpool set cachefile="/etc/zfs/zpool.cache" t0

However that will not work :

titan# zpool get cachefile leaf proteus t0
NAME     PROPERTY   VALUE      SOURCE
leaf     cachefile  -          default
proteus  cachefile  -          default
t0       cachefile  -          default

Let me try just one pool :

titan# zpool get cachefile leaf
NAME  PROPERTY   VALUE      SOURCE
leaf  cachefile  -          default

titan# zpool set cachefile="/etc/zfs/zpool.cache" leaf
titan# zpool get cachefile leaf
NAME  PROPERTY   VALUE      SOURCE
leaf  cachefile  -          default
titan#

So this is even worse.
