Bin Bash ./ in on that, io!

 https://en.m.wikipedia.org/wiki/Su_(Unix)

Is the original source code available for building?

There is  

https://github.com/koush/Superuser

which does not build on my equipment.

I only have fakeroot and not root.

I would like to be able to build with su/root 

access within a jail.

No privilege escalation.

It is to create a complete contained environment 

accessible to the environment on android

for natively accessible binaries without the

"app" process.

All that is available to me is a Lenovo 8505f tablet.

I am destitute, homeless, and poor.

Unless I am able to find it in the trash, it is an 

impossibility for me to buy it.

Android is not designed with Ctrl+Alt+F($NUMBER)

for alternate tty prompts. Surfaceflinger - along with

Wayland - does not use Xproto, multitouch, Xephyr,

 and a lot of useful parts of Xorg/ x11 in their code

bases. This is so sad that a puppy dog is

right now typing an editorial about it in the

" Doggone that shit ain't right, dawg" online 

newspaper.

Humor aside

                         Ha Ha! He He! Ho Ho! Heh Heh!

Is it available, the source code for su that is?

With Xorg/ x11 multiuser functionality with multiuser

with simultaneous multiuser login is possible

with a Linux system using:

1. Base - non GUI - install first.

2. Chroot jail for the embedded chip.

2a.Xorg -config -retro

3. Xproto create in another chroot jail the display,

    keyboard, mouse, monitor, other devices for

   on board/pci etc cards. 

   a. Xorg -config -retro comment out the first

Xorg -config -retro 

The  Xorg proto does not work as well on the BSDs

as it does on Linux for some unknown reason.

Multitouch is the same way.

The original code needs to be separated from the 

Xorg/ x11 code, rebuilt, then added as a subport

for both multitouch and xorg proto.

I have already attempted doing this years ago.

Surfaceflinger peeps, this booger should be spread

on the Android couch.
