Thanks Danny, I appreciate you pushing a fix. I will find out how to make an
updated installer and try again :).
Just to clear up, though, I was going through the guided partitioning, so
didn’t either select to format the partition or try to mount it. It was already
there, I have no opinion on it except that if it disappears my EFI probably
breaks :). But this means that I’m not sure the fixes you described above would
have helped in my situation. Also I would expect to install EFI-based GRUB so
if I want to do that from the GUIX installer (and not, say, boot some other
GNU/Linux installer to install GRUB), I would need to mount the FAT16
partition, or I [or the guided partitioning system] would need to know to
recreate it as FAT32.
I understand that there are firmwares out there (I don’t know about mine) that
won’t recognise small FAT partitions unless they are FAT16. On the other hand,
the UEFI specification seems to expect the partition to be FAT32. So this is a
case of different things working in theory and in practice. Also in practice:
mkfs.fat will make small filesystems FAT16 by default, and some distros
(notably, Fedora, which is what my target machine currently runs) don’t tell it
otherwise. So even if the EFI partition is always FAT32 in theory, there will
be practical cases where it’s FAT16.
Thanks again,
Graham.
