I assume you mean if the files were changed by booting it with a
different OS installation or by putting the drive in a different
machine?  That would be a relatively rare case.

It would probably be enough to have a different selection in the boot
loader, like the one for "profile", which does not use the tarball at
all (and regenerates the tarball later).

How would you do that?
