file: /boot/defaults/loader.conf default settings -- do not change this file.
dtb/ Compiled flattened device tree (FDT) files; see fdt(4) and dtc(1)
firmware/ this file is emty
kernel/ pure kernel executable (the operating system loaded into memory at boot time) and kernel modules
modules/ third-party loadable kernel modules; see kldstat(8)
overlays/ On FreeBSD: Compiled flattened device tree (FDT) overlays; see fdt(4) and dtc(1)
Directory not on GhostBSD
