A lot (but not all) of the device drivers and sybsystems are available as modules. If you look into the example kernel configuration files (GENERIC, NOTES), everything that starts with 'options' has to be compiled into the kernel. Lines starting with 'device' in GENERIC are built into the kernel. All other drivers are by default available as modules.

The FreeBSD kernel is modular but not a microkernel. > If not, is it > possible to build just usbdevs alone? Yes, it should be possible. But I've never done it. It is not advised to build stuff in the source tree. The 'make kernel' process builds a shadow tree for the object files under /usr/obj, but I don't know how to do that for a single module. > I'm a little skittish about fubaring the kernel on my family's main > server. Well, if you're using the GENERIC kernel now, and you build a new GENERIC kernel, it should Just Work. Life can get interesting when you start building your own kernel config. :-) But when I switched from 6-STABLE to 7-BETA, I got decent warnings to adapt my kernel config instead of a broken kernel, so that's ok. And FYI, the previous kernel is saved in /boot/kernel.old/kernel. So you can always boot that. > My name will be mud if I bring it down for a significant > period, and it's my only BSD box at the moment - our data is backed > up, but I don't have a tape drive I can just pull / and /usr off in 5 > minutes if I kill it. First and foremost: get level 0 dumps of all important partitions before you start your adventure! I cannot stress this enough!
