So I expect this to no longer be present; basically cloud-init has changed
to make it much harder / impossible to find this password later.

This output should still be there though, and that's what we should focus
on figuring out. The serial-getty service running on sclp_line0 is what is
_supposed_ to be producing this output.

I guess you should try this on an LPAR install where you can actually get
into the system: can you post the output of systemctl
status serial-getty at sclp_line0.service? And maybe systemctl
show serial-getty at sclp_line0.service? TIA

Title:
  Temporary installer password and key fingerprints are not printed with
  latest impish daily ISOs

Status in subiquity:

Status in Ubuntu on IBM z Systems:
  In Progress
Status in livecd-rootfs package in Ubuntu:

Bug description:
  Using the latest Impish daily ISO (timestamp) 2021-06-24 I faced the
  situation that I didn't got a temporary installation password not the
  key fingerprints at the end of the installer boot-up process.

  Hence I am not able to perform an installation from remote via ssh.
  However, subiqity is started at the console (e.g. Integrated ASCII console) and an installation can be successfully completed there, but a console installation is not in all cases possible, for example with z/VM guests.

  As one can read between the lines I tried this on s390x (Integrated
  ASCII console and z/VM), but 'paride' tried the same on amd64 and ran
  into the same symptoms, so it does not seem to be architecture
  specific.

  This must have happened recently, since I already was able to do ssh-based Impish installations on s390x in the past (for example with the daily ISO from 06-14-2021).
  ___

  This is not the case for the 20.04 dailies - I can do remote ssh installation with the 20.04 live daily ISOs.
  ___

  With Impish on s390x the kernel parameter 'quiet' is still set by
  default.
