Had a problem upgrading a FreeNAS TrueNAS box yesterday which left the system unbootable, so I need to take a look at the boot device, ie a USB stick with a ZFS partition. I have no idea how to mount this. I've done a few searches but haven't yet come across instructions which work.
... but can't workout how to proceed from there...
