Ok, strictly speaking it is different issue with same "high-level" description: pmbr/gptboot has less features than simplest oldest boot0.
pmbr/gptbood doesn't have any way to select partition to boot from, as
"boot0" has. No, setting "nextboot" from live system is not a solution.
I speak about NanoBSD situation when there is tow partitions, both
bootable, one marked as "active" ("bootme" on GPT parlance) but it is
completely broken and user need to boot from other one form very
beginning. This task is trivially solved by "boot0" in pure-MBR case.
What about GPT/Legacy and GPT/UEFI?
