cdbr/cdboot not reading boot.conf

[Matt Van Mater <matt_(_dot_)_vanmater_(_at_)_gmail_(_dot_)_com>]

I'm playing around with making a iso of a bootable cd that should
automatically load a custom kernel, but cannot get the cdboot to read
the /etc/boot.conf file off of the cd.  I'm not sure what I'm doing
wrong here, all the files seem to be in the proper places.  The script
below creates an ISO, that when burned to a cd boots fine using
cdbr/cdboot and I can manually load my custom kernel just fine from
the boot> prompt.

The important part of the script is at the very end where I create the
cd layout and then the ISO.  Most of it is really simple and obvious
so I think it should speak for itself.  I have been testing it from an
unmodified 3.6-release box.  (For the curious out there YAIFO is a
remotely accessable version of bsd.rd, check the misc and tech
archives).  I know I can cheat and just rename yaifo.rd to bsd.rd and
be done with it, but I'd like to know what I'm doing wrong that makes
the boot.conf get ignored.  I threw an echo line at the top of
boot.conf to see if it's even being read, and it doesn't seem to be
the case.
