It's important that you have /usr/src; _how_ you get it is
not important. During installation, src.txz will be uncompressed,
that's _one_ way to do it. SVN checkout is another. And you
can also use freebsd-update to obtain the "src" component.
You only need the source tree if you're going to apply patches
to the source and then recompile the system; the binary update
method does not require it - but it _can_ be used to keep your
local source tree current.
