Had a look at Cuttlefish (see also in German).
That showed me two things. First, professional developers like those at Google use Debian. 😛 And second, it wasn’t worth it – Cuttlefish is no Pixel device.
Anyway, since this is all compiled from source, my computer had to work for a while. I haven’t exactly timed the compilation and building of Debian packages, but my guesstimation would be some 25 minutes on my AMD 8 core with 16 threads and 32GB of RAM. See it working on all cores and threads (the Conky on the right side of my screen):
I ended up with 6.6GB of additional used hard disk space, more or less for nothing – so I removed it all again. Anyway, it has been a while since I heard the fans of my computer (and no, it didn’t get loud).
As always, thanks for reading.
