Couple of comments (gee this looks exactly like my patch that does
this. :))

- you don't need the symlink for the release name on the boot CD
- call it bootonly.iso instead of miniboot.iso, but I think we've
  already agreed on this.
- PC98 doesn't need this ISO image since it can't boot from CD.
  Hence the extra CD_BOOT related ifdef's in the patch I sent you.

The kernel.debug is a feature of GENERIC having 'DEBUG=-g' in it.
For releases, we turn that off, in which case the kernel.debug
will automatically disappear.  I would leave the modules around
since not all modules are in GENERIC on all archs.
