Droidian
Droidian is a GNU/Linux distribution based on top of Mobian, a Debian-based distribution for mobile devices. The goal of Droidian is to be able to run Mobian on Android phones.
This is accomplished by using well-known technologies such as libhybris and Halium.
Note that this is a downstream Mobian derivative, please report bugs and support requests at us, see below for contact details.
