No, the boot partition is not ZFS, and is not written to after the install. (It's a 512k partition, of type bios-boot, that is written to by grub-install during the install (either ISO or 9.2->9.3 upgrade), and then not again. (Yet, anyway.)Could it be a case of Write once as ZFS is know for, meaning that the first install it is located in a memory location accessible to boot or BIOS, but after a few updates, the start location is being pushed further up the memory map (while the former installs are still present and consuming disk space) and goes beyond a limit the BIOS cannot handle?
