Bug Description

[impact]
When there is a serial console configured, there was a unit cycle

serial-getty@$TTY.service -> cloud-final.service -> multi-user.target -> getty.target -> serial-getty@$TTY.service

(or something like that)

Depending on which unit systemd kills to resolve the cycle, this can result in cloud-init never completing which leads to the subiquity server waiting forever for it and nothing useful can be done (other than restarting and hoping for better luck next time).

Because subiquity itself waits for cloud-init (and this has been true for a long time now) there is no need for serial-getty@$TTY.service to wait on cloud-final.service.

[regression potential]
This change results in shuffling the systemd units around a fair bit, but the new arrangement has been tested in devel for a few months now and works well there. It's also much more straightforward than the current setup.

[test case]
This is a bit tricky as it's an intermittent failure. Basically, boot the live installer with a serial console configured a bunch of times and (10?) check that the installer starts up properly each time.

[original description]
From time to time (sporadically and very rarely - maybe in one or two attempt out of twenty) I face a situation where the installer system (on s390x) does not boot-up completely.

This happened to me in the past already, but since it happened only one or twice I thought it's due to resource constraints on the system or so.
But since I faced it now again on LPAR (before it was on z/VM), I'm opening this ticket now.

In the latest case I used the focal daily live image from the 20th of July with installer 20.06.1 (but that also happened with previous versions).

The situation is like this:

In boot of the installer ends here (LPAR):
...

But it is not complete at this point.
A completed boot of the installer system ends like this:

"It is possible to connect to the installer over the network, which"
"might allow the use of a more capable terminal and can offer more languages"
"than can be rendered in the Linux console."

"To connect, SSH to installer@<IP address>."

In such an above situation I also can't reach the subiquity UI:

Just happened again on z/VM using the image suggested to test by QA Tracker from July 23rd.

Starting the installation a second time worked - means the installer booted to the end.

You were reporting this issue well before that got released to stable, so I really hope not.

I suspect this was solved by the client/server split?!
