I've been looking around trying to find some documentation related to UEFI booting FreeBSD without chainloading the FreeBSD bootloader but I was unable to find the answer.
Is it possible to boot FreeBSD with alternate EFI boot loaders without chain loading? I use the bootloader gummiboot, now systemd-boot on Arch Linux and I was wondering if it's possible to boot straight into FreeBSD. I know it's possible to chainload into the FreeBSD bootloader, and boot from there, but I was just curious from a technical point.
When trying to boot with gummiboot here are the instructions:
Beyond these entries, you must create entries for Linux kernels or other boot loaders by creating configuration files whose names end in .conf in the ESP's loader/entries directory. For instance, you might create files called loader/entries/fedora.conf and loader/entries/custom-kernel.conf. These files include keywords to set a title (title), to launch a non-Linux EFI program (efi), to launch a Linux kernel with EFI stub support (linux), to pass options to a Linux kernel or other EFI program (options), and to specify an initial RAM disk (initrd). An example looks something like this:
It can boot from ZFS like this:
