I do have buildworld results, but since I run -current, I have
debugging options enabled for the kernel, which seems to have a big
impact on its size on disk. The original question (how big is / on a
default install) did not seem important enough to spend the cpu time
building a non-debug kernel. Luckily for me, several people know
faster ways.
