The verification passed for focal. The following steps were taken for
verification:

  1)boot to safe graphics mode
    a) observe that no startup sound is played
    b) `watch -n 1 'systemctl status sound.target'`
      1) wait for sound.target to become active
      2) observe that no startup sound is played after
         sound.target becomes active
  2) download source for ubiquity version 20.04.15.11
    a) copy the changed files gtk_ui.py and misc.py
       to a flash drive
  3) reboot to safe graphics mode
    a) add `break=init` to the kernel command line
    b) in the initramfs, copy gtk_ui.py and misc.py from the
       flash drive to the root/ file system
    c) exit initramfs and allow boot to continue
    d) once the boot process has finished, observe
       that no startup sound is immediately played
    e) `cat /proc/cmdline` to ensure that `nomodeset`
       is on the kernel command line
    f) `watch -n 1 'systemctl status sound.target'`
      1) the startup sound is played when sound.target
         becomes active. Success!
