I have two bootable disks, and SSD with F32 (and Win 10), and a HDD with F31 and a few
other distros. Each disk has its own EFI partition. F32 mounts the SSD's EFI partition
at /boot/efi; F31 mounts the HDD's EFI partition at /boot/efi. Both Fedoras have the
appropriate entries in their respective /boot/loader/entries directories, and in both
cases, GRUB_ENABLE_BLSCFG is set to true.
If I update the F31 kernel, then boot off the SSD, I am not offered the option of booting
F31 with the new kernel unless I regenerate the SSD's boot/efi/EFI/fedora/grub.cfg.
What I want is for the SSD's bootloader to automatically offer me the option of
booting any kernel configured in the F31's /boot/loader/entries, rather than offering
me only the options in its own /boot/efi/EFI/fedora/grub.cfg.
Is this even possible?
