Manage recovery OS without Debian package

[m-roberts]

Recovery partition has its files mounted from partition 1 onto the OS, so the OS might think that they are a different version.

e.g. pi-topOS fully updated let's say has recovery 4.3.3. you use recovery to reset your OS, and you boot into the one that had 3.2.0. the list of files that the OS thinks should be in that directory controlled by that package could be totally wrong

The recovery partition's files need to be "independent" but managed. Instead of files being provided directly by a pt-recovery package, this should be replaced with a system that handles the files in the recovery partition.

This is done as of v2 for Bullseye - no solution yet for Buster updates!
