Currectly hw-probe detects an EFI system by checking either:
/boot/efidirectory, orefi:line in kernel log.Both methods however, are wrong, leading many non-EFI systems being misdetected.
For the presence of
/boot/efidirectory, it means the system may have a setup that supports booting via EFI; it doesn't necessarily means the running system was booted via EFI.For the
efi:line in kernel log, it only means the running Linux was configured to be EFI-aware. In fact, theefi:line of one of my system is:Which actually indicates that EFI is not being used.
Remove both improper checkings, and check for
/sys/firmware/efidirectory instead.
