Title:
  Warn if the installation source device is selected as installation
  target

Status in subiquity package in Ubuntu:
  New

Bug description:
  Traditional ISO installation tools could install only on USB flash
  drives. However, balenaEtcher, and Ventoy, can also install ISO on
  internal hard disk drives.

  The benefit of installing from internal hard disk drives is that they:

  * can always be mounted in the computer, so they will always be
  accessible

  * they are faster than USB flash drives. Even the fastest USB flash
  drives are using compact internal hard disk drives like NVMe M.2.

  Issue

  The issue is that GNU/Linux distribution installers are designed for
  USB flash drives, which means that they will not add a warning text
  next to the title for internal hard disk drives even if they are used
  as installation medium.
