I wish I had the docs stuff setup -- I would generate a draft for that
if sgml functioned for me. The docs really need dusting off for 9.0 in
the booting and rc area.

The base premise is: put everything in /boot/loader.conf that's
required to initial mount the system (aka mountcritlocal).

Which means in the following generic, simple use cases:

1. When booting off USB media, you must put the USB stack (ehci, uhci,
xhci, umass) etc in /boot/loader.conf (wash, rinse, repeat for
firewire).
2. When booting off CD/DVD media, you must put the appropriate drivers
(e.g. ata_cam, ahci, etc) in /boot/loader.conf .
3. When PXE booting, you must put the proper network driver (e.g.
if_em, if_msk, if_re) in /boot/loader.conf .
4. When booting off a local disk, you must put the appropriate disk
controller driver (e.g. ahci, ata_cam, mfi, twa, etc) in
/boot/loader.conf .

If the requirements for the boot process are non-standard (i.e. your
boot starts out as PXE, then switches over to disk access), then a
cross product of those permutations should be performed.
