✨ Add support for multiple overlay devices
Support is being added for multiple overlay "devices". More complex scenarios like mixing and matching various devices with, e.g. "tmpfs" or multiple crypt devices, are not supported.

🚸 Improve ro detection for when both are present
Improve root file system "ro" detection for when both "ro" and "rw" are present in the kernel command line.
The above is helpful for situations when one only controls an append to the kernel command line and is not in complete control of the entire command line to be able to remove the "ro".

A package used for testing purposes can be found here:
