#
#The following pieces are still missing:
#
#- MILO bootloader & images.  I have no way to test this directly, and
#  haven't used MILO for years, so I'm giving this a pass on the first
#  run.
#- Floppy images.  Currently, debian-installer claims not to support
#  the floppy target on alpha, which is arbitrary, but there may just not
#  be any reason to continue supporting this install method.  Another
#  decision that can be made later.
#
# $1 is the CD number
# $2 is the temporary CD build dir
