Awesome!  Thanks!

I think the best fix is to change it to apply to ${CLFS}-final.  I'm
not sure if the nodes stay correct when tar'ed up.  If they do, then
moving it before ${CLFS}-final is doable.

I think your sed line is good.  It's easy to understand and read for
those who also aren't sed experts.  I'm not a sed expert.

At this point, regarding the sed line and the mknod commands, I think
these discussions should either move to the -dev mailing list or into
individual trac tickets.  We've worked through the support side and
found things that need to be updated in the book.

Thanks,
Andrew
