I do have a wrapper around the macppc build that fiddles with making the cd
bootable.  What other platforms need such helpers?

Unless augmenting is really easy it might be a good point to
introduce a call a hook or just have a different tool.  My "BUILDCD" script
ends up generating:

    /builds/current/src/ -j 3 -u -U -N 0 -x -M \
    /builds/current/i386/obj -m i386 -D /builds/current/i386/dest -R \
    /builds/current/i386/release -T /builds/current/i386/tools \
    kernel=PETER-FW2 releasekernel=PETER-FW2 kernel=PETER-FW \
    releasekernel=PETER-FW release

(Where the kernels are glob'd based on what conf files I've built.
Unfortunately I copy them into the src tree and then delete them after the

Adding another arg or sets of args to might be confusing to someone
who is simply trying to take a release and re-roll it.  Perhaps something
that uses pkg_comp might make sense?  It's framework already creates an
environment that seems to be suited to be an arg for makefs.

Maybe I'm missing something simpler or too obvious for me?
