Comment 13 for bug 1887669

@mwhudson
LP 1878596 is not exactly a duplicate, since some more issues and concerns are raised there, like:
a) lack of information/knowledge on subiquity and the differences compared to d-i (at that point in time <20.04 GA> a parmfile was required for installations)
b) the use/support of very special DASD ECKD disks (3390-ModA EAV and EAV-II DASDs)
c) and the fact that DASD ECKD disks need to be pre-formatted (as of today)
Only c) is a duplicate to this one here (LP 1887669).
Fortunately the a) and b) are sorted out - so only c) is left.

Since this bug here (LP 1887669) is exclusively about the low-level format bug of pristine DASD (ECKD) disks, I would suggest that is used as anchor for these activities.
Once it's solved/fixed we can close the other one (LP1878596), too.
