Mageia forum

First there was a remix os but it was discontinued and there are three forks so far : bliss os , prime os and phoenix os.They are all based on android x86. Installing them on mageia is easy . Here are some links.
https://docs.blissos.org/install-bliss-os/manual-install-on-linux
https://itsfoss.community/t/install-primeos-on-ubuntu-or-any-other-distro/7405

Those two tutorials contain the most succesful boot sequences. The boot sequence for bliss os is more universal it worked on phoenix os , after changing blissos with the new folder name phoenixos in the sequence. I did not have much luck with other boot sequences provided in other tutorials .
If you use Timeshift for snapshots you can easily exclude the android folder in the settings. And another advice if your computer is a little too old do not download the latest isos available on the website . Go to their sourceforge pages click on files and choose an older one. Prime os has mainline standard and classic editions where it is a little difficult to choose the right iso for bliss os.

But I have many questions about this method.
1. Will it work on btrfs?
2. What will happen when I upgrade mageia from one release to another?
3. Are the files and apps installed on this system put in the data folder or data.img and do .img files grow in size like folders as well ?
4. Does it impact mageia performance in the long run?

1. You have to look into the documentation of the OS
2. Shouldn't make any problems.
3. ISOs and IMGs don't grow. They are only installation images. It's documented in their installation instructions.

I personally don't find any Android game so good that I would clutter up my machines with something like this. Given the lacking hardware support and old application versions i wouldn't install any of these OS. Steam nowadays gives you the possibility to play up to date games on Linux.

Steam is heavy on older machines and does not have many free titles.There are some soccer games available only on android that are easier to play than fifa and efootball. These systems provide key mapping support so you could play with your keyboard as well. Finally, if you have a drawing tablet that is supported by these systems you can use some of the drawing apps available on android.

Steam runs well even on 10 years old hardware. Steam also provides a lot of free titles. Sure if you want nonsense like Candy Crush and Co you need Android

And most Linux distries have already Touchscreen support.

And don't forget stickman soccer.
