[Bug 2031541] [NEW] output from dmesg (log) interferes with login

[Mr John Paul Cooper]

Public bug reported:

On Ubuntu 22.04 Server but also affects earlier releases the login
prompt gets masked and/or interfered with by outputs from dmesg or log
outputs on screen. The package being used is version 249.11-0ubuntu3.9
(systemd) and 23.2.1-0ubuntu0~22.04.1(cloud-init).

These can come from official software (cloud-init) but also from
partner's software (e.g. hp-ams and/or amsd). It really interferes with
logging in through KVM either through remote means or local, but not
over SSH. Including HPE's iLO and Dell's iDRAC.

It's especially problematic when trying to type the password after a
reboot or cold boot.

What I was expecting was for those outputs during login prompt to be
logged to log file only, to be accessible afterwards via dmesg or
equivalent.

What happened instead was issues with repeated incorrect password or
username due to the masking of what displayed on screen.
