Modular kernels have to have module(s) loaded via the bootloader
if the kernels don't have builtin modules for the root file system,
where the kernel is loaded from. All other modules can be loaded
from the root file system after mountroot().

So necessary info might be "which file-system modules are builtin?"

(though I'm not sure if options NFS_BOOT_DHCP requires bpf(4) module or not)
