The default sequence of boot methods is determined by alphabetical sorting during linkage.
- efi_mgr must run before efi to be UEFI compliant
- pxe should run as last resort

This sound very much like you're working around a standard boot design flaw.
Who does the alphabetical sorting here? Is that just a result of how the toolchain behaves? If so, that sounds fragile to me and I think it would be better to make the order explicit in the code.
Cheers,
