Bug#666879: s390(x): please add a netboot image

[Philipp Kern <pkern@debian.org>]

Package: debian-cd
Severity: normal

You can boot CDs on s390, which is why we generate ISOs.  However, nobody
implemented to actually pull the debs from the disc.  Instead booting CD1 is
basically equivalent to booting a netboot image.  You can, of course, copy the
debs onto some FTP and then install from there.

Hence it would be useful to provide a real netboot image that only contains the
usual documentation, the d390.ins and the boot subdir of a normal CD images,
but no further debs.

Please note (for someone's reference) that copying the .ins and boot from the
CD to a FTP server does not seem to work when trying to boot in LPAR mode.  CD
booting does work with current squeeze images, however.
