First off. a couple of things. This is not a tutorial because every phone is different but feel free to use and modify my scripts to fit your needs. This is not my 1 year linux challenage post. I have something that should be a bit grander in mind than this.
I want to give HUGE thanks to the debian wiki people for making this post which basically did most of the work and guided me to the final solution. Now lets move onto the actual post.

This is my post about how i managed to integrate standard debian linux into a android system without tainting android in a way that makes it more broken and unusable. I have 2 files that help me do this. There is mount.sh and file. File is called file cause i cant name shit
mount.sh has 2 main jobs. mount the sdcard and intagrate linux into root directory. it links /bin, /etc, /usr, and etc to the linux operating system stored on the sdcard. from this point you can do a couple of things like export PATH, HOME, and anything else you need and it 'should' work though i have not done much testing with this.
file is the main program. It sets up stuff like home, path and everything the programs need to run.
So far programs like apt-get, gcc, nano and that kind of stuff work. i have not done much work with gcc yet to see if it uses the bionic libs in android or the libs in the debian install but it will compile a hello world program correctly.
I will continue to update this post as it try more stuff out like ssh, xorg and all of that fun stuff.
