Agreed.. although something needs to be done about it - eventually
(otherwise dependent packages just won't install)

Output attached - 3 files (with hopefully self-explanatory file names)
If file attachment is not accepted by BTS, I will look in the FAQ on how to
achieve this (I am no real expert in reporting bugs !)

s390/s390x may need (from what I can gather)

- dasd_eckd_mod (ECKD Device support) < That's what I need in my particular
case
- dasd_fba_mod (FBA Device support)
- dcssblk (z/VM Shared segment support - although I'm not sure if this can
be used as a rootfs)
- xpram (Expanded storage - same restriction as above)
- zfcp (QDIO/Fiber Channel devices - SCSI over FC)

Because of the architectural constraint related to S/390 & z/Arch these may
be the only ones needed - all I/O is standardized on this architecture.

I did (this option was suggested by the debian-s390 people) ! Although the
initramfs gets built, it fails to boot (the module is not included as part
of the ram root fs)

Of course, should you need more information, I'll be glad to provide you
with anything you need !

Thanks for your help !
