    If you upgrade your ports tree and then rebuild your kernel you may upgrade a
    port KLD without wanting to.

    http://www.dons.net.au/~darius/port-makefile.txt

    (Rename the later to Makefile and put it in /usr/local/kld)

    It hooks into /usr/src/sys/modules/Makfile and looks for module directories to
    build in a certain directory. It [is supposed to] acts like another
    subdirectory of /usr/src/sys/modules.

    I am pretty sure it does but I haven't explicitly tested it - certainly the
    source directory doesn't get dirtied by builds.

    Ahh.. I NFS mount my ports tree between a bunch of machines they all have
    WRKDIRPREFIX, and the ports tree is updated each day using cvsup.

    I don't think this is an uncommon setup but I don't have any evidence.

    Yeah usually, but I have had it happen in -stable too (very rare). Even so it
    can be a pretty big waste of time as a developer when you're tracking
    current ;)
