I had a similar problem back then, see how I fixed it here:

The most sane way is probably to only install 4 OSes, which is usually
enough for a smartphone. For everything else you need a custom solution,
which might get difficult.

All I know is this project:
https://redmine.adorsaz.ch/projects/b2g-manifest

It wasn't officially announced, yet and doesn't seem to be very active.

>> (6) Some notes on the upgrade instructions (the System Manual, Rev 4):

>>         → carefully position *where exactly*?
