Hi Ulrich,
thank you for your input!
I used the flag "bios_grub" because of
https://www.gnu.org/software/grub/manual/html_node/BIOS-installation.html ,
you're right about it not being exactly correct.
Thomas suggested "efi", it's his decision to choose which term to use.
I have only very limited experience (honestly, none - I don't use it)
with GPT and as such rely on information from others. We hadn't realized
the redundancy of the feature and it seems to be the case for a few
people on the mailing list who use GPT. I'm guessing that there is some
lack of documentation or not enough clarity or something. Either way,
we'll look into it.
Again, thank you, much appreciated.
Best
Kerim

We'd appreciate it, if you guys could test it and reported any bugs you
encounter.
I have some remarks, and one bug report.
To create an EFI System partition (ESP; gdisk partition type EF00) with
parted, you need to set a partition's "boot" flag (see [0]). The bug is:
The new code sets a partition's "bios_grub" flag, resulting in (gdisk)
partition type EF02.
Also, I feel that "esp" is a better identifier than "efi", as the former
abbreviation appears in other literature and seems less ambiguous.
I have attached a patch that addresses these issues (based on
2dadbeeaddaa7f6c778146ad35782281de5b074d rather than HEAD because I feel it
shows the differences better). Please feel free to use it if you find it
helpful.
Additionally, I want to point out that you can create an EFI System
partition without the new feature with the "bootable:<number>" disk option,
like so:
disk_config disk1 disklabel:gpt fstabkey:uuid bootable:1
primary /boot/efi 200 vfat rw
[...]
Regards,
Ulrich
