Meoboot is what on a PC would be a Multi-Boot configuration. It provides a user choice at booting time for various operating systems with different releases and/or patches.
Parallel Universes on the other hand is the PC equivalent of Multi Users defined on a single OS. All users share the same OS and patches but configurations and applications made available will differ per user. Just like on the PC using a simple labeling interface the various Universes could also be personalized like: Dad, Mike, Gloria and Peter.
Be aware that Enigma OS and hardware related changes must be done from within the Black Hole Universe. This is different on a PC where this is done implicitly in a transparant way.
I am familiar with what Meoboot and what Parallel Universes are...
In previous versions of BH, I was able to update each universe separately, and the Information panel displayed the version of the updated image. That means when I updated - let's say - Avalon universe then the appropriate packages were downloaded and in the Information panel I could check that the updated version was displayed. The same applied for every universe, including Blackhole universe of course...
What I noticed with version 2.0.2 is that Blackhole universe is normally updated, but every other universe can't find the update to revA.
The only solution I could find (and I followed) was to update Blackhole universe and then do a Big Bang. After that, every universe is updated in revA, and it is confirmed in the Information panel. The disadvantage of that method is that I had to setup Avalon universe from the beggining (I used to setup Avalon for everyday use)...
Another solution could be to make a personal backup of other universes, then restore after updating Blackhole and initializing a Big Bang. But this gave me green screens. I hope I have the time to investigate this during weekend...
So, I settled with the following setup which seems to be the more stable and comfortable use of BlackHole image for my needs:
- BlackHole 2.0.2 revA in flash, nothing extra installed (plugins etc) and used as a "base" for Meoboot and Parallel Universes (Parallel Universes are important for me as I want to be able to try different plugins or extras and try some linux tweaks for my Uno)
- BlackHole 2.0.2 revA in Meoboot for everyday use (instead of using Avalon as I was used to do up to now)
This way I have maximum functionality and fun with my STB and I can update everything with no side-effects when BlackHole team will release future minor updates for 2.0.2...
