Eh, all I needed was "/dev/dasd*" for the first question. But thanks. > The other > three formats, by definition, only have one partition.

So for CMS formatted "unpartitionable" disks we get exactly the same devices as for "partitionable" dasds with only one partition. We should get: /dev/dasdX /dev/dasdX1 But you said in your earlier mail: Partman does not recognize that the disk already has a "partition" on it. To me that seems to indicate that /dev/dasdX1 does *not* exist as otherwise I would expect partman to list it. Or maybe it is somehow invalid. And to avoid users repartitioning the device the question remains: how can we "see" (in sysfs or otherwise) that this is a CMS formatted device that should not be repartitioned. Is there for example a difference between cdl and cms formatted partitions in one of the files in /sys/bus/ccw/devices/<dev>/? Or maybe one of the files in /sys/block/dasdX (capability, range or ext_range perhaps?)? I would really like to know *exactly* what devices exist in Debian Installer when you get to the partman stage. The /var/log/partman log file as it is at the point after partman has initialized itself would also be useful. I guess you'll have to set up a small scratch system you can play with and run repeated installations on while we're working on this. I would suggest to create a system with exactly one new CMS formatted mini disk.

Do I have to run D-I? On the installed system will be fine for now. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
