Well, I was pretty frustrated at that point :) But there are some things
that would make it easier...

For one, why did my PARTUUID change? I used gparted and moved both /boot
and /boot/efi over to the new disk. The UUID was unchanged, and I had no
idea that EFI used PARTUUID.

Also, why does efibootmgr silently act like it's working? I tried
"changing" an entry and it exited like it worked but couldn't because
efivars was still mounted RO... I can't remember what I did but a different
command (maybe remove?) was the one that got me the hint that I needed to
remount efivars as RW.

Thirdly... I wasn't sure if partitions in EFI start with 0 or 1 and it I
couldn't find ANYWHERE that said one way or the other...

Thanks,
Richard
