This makes it really difficult to potentially support building FreeBSD images on non-FreeBSD platforms. It also means that people can do things like have out of date builds of things like bootloaders, mkuboot/mkuzimage, etc. That's why I'm kind of a bit worried about this trend. I'm likely going to go the opposite way with my stuff. Ie, if I do need bootloaders and such, I'll be packaging either the source trees, or ports themselves, as part of the "freebsd-wifi-image" build environment. I'll try to reuse the port build infrastructure as much as possible but I won't rely on many tools and external support software trees that aren't in /usr/src or the build environment itself.
