@a1ba @ThatOneSeong Well even non-GNU systems like Alpine or OpenWRT just runs most Linux software compiled for it without any modifications.

Sure there's some exceptions but same kind of thing as software which just breaks tomorrow because some poorly/non-documented behavior changed or some software broke API.

Difference with Android is more that you're not going to have anything freedesktop (X11, pulseaudio or compatible, dbus, …), not going to have perl/python/…, and as it's a ficher-price OS you can't even install a C Compiler either.
(termux being effectively installing another OS)
