/boot/loader	The program called loader is the final stage of FreeBSD's kernel bootstrapping process.[1]
/boot/loader.4th	loader(8) bootstrapping script. loader.conf processing tools
/boot/loader.conf	user defined settings
/boot/loader.efi
/boot/loader.rc	loader bootstrapping script. Standard: /boot/loader.rc: include /boot/loader.4th
