NOTE: This is with FreeBSD 14.1-BETA2

I am not 100% on this yet, but I think I am seeing a bit of a visual bug in loader.efi.  On an Intel NUC8i5BEH, I build and use a custom kernel that is installed to /boot/kernel.custom.

In /boot, I create two symlinks:
  - "GENERIC" which points at /boot/kernel
  - "CUSTOM" which points at /boot/kernel.custom

In /boot/loader.conf, I set these three variables:
> kernels="CUSTOM GENERIC"
> kernel="CUSTOM"
> bootfile="/boot/kernel.custom/kernel"

Under 14.0-RELEASE, the boot menu would show for Item #6, this text:
> 6. Kernel: default/CUSTOM (X of Y)

But under 14.1-BETA2, I see this:
> 6. Kernel: default/GENERIC (X of Y)

Which shouldn't happen, because the default kernel is the first element in the 'kernels' variable.  However, despite what the menu shows, the correct kernel, pointed at by "CUSTOM", is what is booted (likely because of the setting of the 'kernel' variable or the bootfile variable).

So I think this could be just a visual bug, but I am not 100% certain at the moment.  I haven't updated a system using the classic BIOS loader yet to see if it's got the same bug.
