CC @current, as I had originally intended.

Normally LOCALBASE is interpreted by ports as the default for PREFIX, meaning it should be a path _within_ the target system, not the path to where it is mounted. There is DESTDIR for that. Now for kernel build this is not a problem for the reason that LOCALBASE is being used just to find sources, not to build ports. However, given how that variable is normally used, it seems like a problem waiting to happen. It would be better to use a variable specific to the purpose at hand. >> How about when I'm doing a build of 11-stable for testing, but what's >> in my /usr/local is sources for a 13-current driver? > Given that the kmod's are supposed to be portable across branches, > the build really shouldn't be breaking.

The concern appears to be that there is no longer a clear way to separate what base source tree does from what is in the local system's configuration. Is there any one single knob to tell /usr/src not to use any configuration from /usr/local?
