For a Unix system to be functioning, it must have a mounted root file system.

Always. This has been the case since Unix was developed at the end of
the 1960s.

Which root FS can change -- the ``chroot'' command can do this, for instance.

However, it need not be mounted read-write. It can be mounted
read-only. You can fsck a filesystem which is mounted RO. This is
normal in maintenance mode.

``dpkg'' on its own does nothing useful.

``clean'' is not a Unix command, TTBOMK.

Finally: please bottom-post on mailing lists.
