Title:
  Ubuntu Studio images aren't being built with a live user

Status in debian-cd package in Ubuntu:

Status in livecd-rootfs package in Ubuntu:
  Invalid

Bug description:
  This is a tracking bug to figure out the issue with Ubuntu Studio
  noble images not being built with a live user.

  This appeared after we started the transition to using ubuntustudio-
  system-installer (a fork of ubuntu-flavor-installer, itself a layer on
  top of ubuntu-desktop-installer). With Steve Langasek's guidance, we
  merged the code to livecd-rootfs to get .iso images building with
  ubuntustudio-system-installer, but the system boots to a blank black
  screen with a mouse cursor themed with the Breeze cursor theme from
  KDE Plasma Desktop, meaning something is attempting to be loaded here.

  However, switching to a VM results in a login prompt, but attempts to
  login as "ubuntu-studio" as in the past proved in vain. Upon
  investigating the squashfs image, no user directories populate the
  /home directory, suggesting casper never creates the ubuntu-studio
  user.

  This is fixed by changing the KERNEL_PARAMS line to the following:

  > KERNEL_PARAMS="${KERNEL_PARAMS:+$KERNEL_PARAMS }layerfs-
  path=standard.live.squashfs --- quiet splash"
