[Bug 2013403] Re: lunar riscv64 preinstalled image shows login prompt before login is possible

[John Chittum]

this is actually true of pretty much all cloud-images, at least that i'm
aware. I've seen this functionally on every cloud image, all arches,
since i joined CPC.

I think it's generally not considered a "bug" for cloud-images, as the
standard user interaction is via SSH. for that use case, a user is not
able to SSH into the image until cloud-init has finished provisioning
SSH keys, and so most users will not have an issue.

I'm with vorlon on this generally -- if we view reaching the login
prompt before user finishes configuration as a bug, it's a bug in cloud-
init / systemd (with some sort of blocking mechanism therein) to
disallow a terminal console from showing a login prompt. as far as a
cloud-image, it's "operating as expected" though less than optimally.

Bug description:
  Testing the lunar unmatched daily image in qemu, I was given a login
  prompt on console and tried to log in, and it repeatedly failed.

  This is because cloud-init had not finished running, so the user that
  was provisioned via nocloud data was not actually available.

  There should not be a race.  The login prompt should not be shown
  until after the user exists - either by changing the ordering of the
  systemd units, or by not using cloud-init to configure the initial
  user.  (I don't see any obvious reason that a hard-coded initial
  user/password should be done via cloud-init instead of being
  prepopulated in /etc/passwd, but feel free to enlighten me.)
