Noted. However, the driver here is an automated loading system. This isn’t a theoretical ‘least you can have in the kernel’ thing but rather GENERIC with all the stuff you can practically kldload taken out. But you bring up a good point. i386 is easy, once the basics are done. PowerPC is only slightly harder, since it has good /boot/loader support as well as a GENERIC kernel or two. Ditto sparc64. But stepping into arm and mips then all hell breaks loose. It’s also desirable to refactor GENERIC, for the transition period, to be include MINIMAL + more stuff. I’ll do that as time permits.
