I have been on a mission it seems to find the smallest fastest linux to install Waydroid and thus current Kindle4Android. All this cause stupid Amazon has once again made current generation Kindle4PC incompatible with WINE. They really should just made a linux version in first place.
Seems as far as I can tell at this point, Waydroid needs a linux with systemd. I first got it working on Fedora 39 workstation with GNOME. Ok, probably way to go if you have touch screen. GNOME Is touchscreen friendly, not so much for trackpad or mouse. Then got it going in MINT with cinnamon. Need weston compositor. Ok. Then tried on MX23. I couldnt get it to run until I booted MX with systemd option (it gives this option in GRUB menu). Then tried Bodhi, its up to v7 now. This thing has improved and very fast both to boot and to get to Waydroid Lineage desktop and Kindle4Android app. I mean Puppy kind of fast. I was impressed for a distribution based on current Jammy Ubuntu. Enlightenment-Moksha destop takes some getting used to and like all distributions has its quirks including some inherited Ubuntu quirks. But it has apt-get with Ubuntu repositories. Its speed and ability to run Waydroid has earned it a long term place on my most used laptop.
I messed some trying to get Waydroid to work on something in Puppy family, but so far havent succeeded. I think quite difficult since it doesnt use systemd. Though I read couple mentions of somebody using it in VOID, and I dont think VOID uses systemd. Correct me if I am wrong. Havent tried current VOID install yet. Oh and recently noticed a community editon of Manjaro that uses a i3-like Sway wayland compositor desktop. i3 is pretty unique, so a Sway version even more so. I imagine it should be very Waydroid friendly.
