So zfs_parse_bootfs says it wants to convert the boot path passed from
the bootloader, which has form rootpool-name/filesystem-object-number,
to a dataset name rootpool-name/root-filesystem-name. It returns
EINVAL if the boot path is the empty string or just "/", and maybe
also for other reasons from the stuff it calls. Looking back to the
caller zfs_mountroot it is getting the boot path with
spa_get_bootprop("zfs-bootfs");
I *think* that value comes from the grub menu.lst, as in -B $ZFS-BOOTFS on the
kernel line based on the earlier bootfs line. So if this happens again I'd
stop under the grub menu and have a look at the entry being used to see
if the bootfs etc lines look ok. I'd also say this is very possibly a symptom
of not following the upgrade procedure.
