That's a useful size for experimenting with systemd-boot, which
expects kernels + initramfs and BLS snippets to all go on the EFI
system partition. The Fedora installer's default for the EFI system
partition is around 200MiB, and the most I've seen Fedora's
bootloaders use is ~14MiB.
I'm going to look into alternatives since I seem to be having such
little success with the default. I'll investigate sd-boot.
Some firmware only boot CD's with CSM. Other firmware, you must use
the built-in boot manager, which shows what firmware type will be
presented when booting the CD, i.e. you'll see the CD listed twice.
Once with UEFI listed; and also without or possibly with the word
"Legacy"
Solved this at least. If I edit the boot line, and knock off quiet,
I see something close to "EFI stub: Booting UEFI in secure mode", so
I know that I'm booting in UEFI now.
After you boot installation media you can check what firmware is
presented with # efibootmgr
If entries appear, it's UEFI. If an error appears, it's CSM/BIOS. And
if it's CSM/BIOS then defining a /boot/efi mount point is invalid. If
you want a UEFI installation, it's mandatory that you figure out a way
to boot the install media in UEFI mode. Even if it means you have to
create a USB stick, and must abandon CD booting.
This is a handy way to check and confirm. Good for future reference.
But, as I mentioned in other posts, on hold for now.
