Having found the undocumented 'verbose=2' option:

Writing boot catalog to sector 19
Writing catalog entry of type 0
Writing catalog entry of type 0
Finished writing boot catalog
Writing boot image from /usr/src/releasedir/i386/installation/floppy/boot-big.fs to sectors 20
Writing file: /usr/src/releasedir/i386/installation/floppy/boot-big.fs
Files written
Image closed

image yields a bootable CD using

mkisofs -o output.iso -b i386/installation/floppy/boot-big.fs \
  -c boot.catalog -l -J -R -L \
