[Bug 2111695] Re: [Ubuntu24.04] - curtin - subiquity installation with multiple dasd sizes leads to an error in partitioning

[Frank Heimes]

Okay, so esp. due to comment #4:
https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/2111695/comments/4
that even more makes me think that the order of enabling the DASD disk is not correct.

The autoinstall file is often generated with the help of an interactive installation.
And if one enabled in the installer text UI the DASD disks like this:
1. 0001 / dasda (mod 54)
2. 0002 / dasbb (mod 27)
but the the disks are enabled in the early_commands section of the autoinstall yaml file in a different order, like:
  early-commands:
  - chzdev dasd-eckd --enable 0002
  - chzdev dasd-eckd --enable 0001
And using an above autoinstall scheme
DASD 0002 will become dasda, now be the smaller disk and
DASD 0001 will become dasdb, now the bigger one
hence the disk geometry stored while the autoinstall was created does not fit anymore.

The order of how the disks are enabled need to always stay the same.
