Hello all,
I have been looking at some of the issues with UEFI booting of Haiku.
My thought is that the best approach to UEFI booting is to store a
partition identifier in a file next to the haiku_loader.efi/bootx64.efi
on the ESP partition. This file can be read via the UEFI BootServices.
Then the file system(s) can be mounted and the VFS searched for the
required partition.
I have created a prototype implementation (using the partition name as
the identifier).
I have pushed this to Gerrit for your review.

This implementation requires one extra step (which will be handled by
the Installer) when installing to hard drive as described here:
https://www.haiku-os.org/guides/uefi_booting/
After copying the BOOTX64.EFI, also copy partition.txt and edit it to
have the name of the partition to which you just installed.
Cheers,
Joe
