[Bug 2025706] Re: Live session doesn't start on mantic arm64 desktop daily

[Tim Andersson]

I'm having virtualization issues but I believe I've run into the same issue despite this:
```

Running on the same system as mentioned before with emulation.

Title:
  Live session doesn't start on mantic arm64 desktop daily

Status in syslinux package in Ubuntu:
  Confirmed

Bug description:
  Upon booting the Mantic arm64 desktop daily ISO (dated 2023-07-03),
  the live environment is not started. Instead, the graphical login
  displays a username/password prompt. None of the usual suspects
  (ubuntu or mantic) are accepted.

  During the boot, several messages appear on the text console
  indicating that username "ubuntu" was not found. If the ISO is booted
  to single user mode, /etc/passwd does not contain any username
  'ubuntu'.

  The ISO is being installed on a virtual machine - VMware Fusion 13, Mac mini M1 (2020) Apple silicon CPU. 
  Mantic server daily builds do install and work properly, so whatever the issue is, it's with the Desktop daily build.
