Hello. I'm a bit confused about zpool.cache file. I've got a configuration with /boot sitting on a usb dongle (UFS) and everything else on internal ZFS hard drive. I'm booting my system off the usb drive so zpool.cache file is there (it was generated when I created zpool). Basic zfs root + ufs boot setup. Everything works like a charm no problems so far and I would like to keep it that way hence my question. I've noticed that zpool.cache on ZFS drive is being created and updated from time to time and it is different from zpool.cache file on usb drive. Even when I remove zpool.cache file on hard disk then it gets recreated automatically and system still boots and works fine since it starts with zpool.cache on usb drive which is intact. Now how important it is to keep them in sync and what I'm risking by not doing that? Should I copy zpool.cache from hard drive to usb boot disk every day or should I leave it how it is and don't even bother?
