Not sure "multiboot" is the accepted term, but I have the impression that there's an issue with the current "zfs Grub" version behaviour when there are multiple disks with bootable partitions when doing update-grub . When I'm booted off a standard ext4 partition, the (mounted!) zfs partition is ignored , idem for the ext4 partition when I boot off the zfs volume.

Is this the normal behaviour?
