This is a fantastic change.  Our new-branch-per-project methodology
@work made us implement this change locally.

Another change that was necessary along the same lines was to remove
any hostnames or path names that leak into object code, the most noticeable
of which is of course one of the first kernel boot message lines.

Are there plans to change kernel code and/or hostname/path name stuff?
