It is not possible to compile any software without the header files. As the installer does not know if you want later to build ports from sources or compile your own software, the header files are installed. > Unfortunately, it is not possible to rerun freebsd-update on the same > version to correct a problem such as this. > > I am not sure whether /usr/src/sys is considered part of the "world" > or "kernel" components or not; if it is not, then the above would > explain the behavior.

This could be the reason why they are there. I am a bit confused about how you update and why. If you compile your own kernel, just use svn to keep the sources current. If you do not compile your own kernel, just ignore there things as they will not affect you. Erich
