How to run nix on android with root and without termux and other garbage

[smopro]

I have some android devices with normal terminal emulator (extended mods for support a11+ from here ) , root and entware. I don't want use any garbage tools like termux (i have in use android 4.4 and what is termux garbage), proot and other "root emulation". I just want make "full desktop" system alongside with android and use from second monitor\keyboard\mouse with xserver xdsl and xfce (or another DE).

This is currently out of scope for this project, I am sorry.

Can you explain mechanism of work this project? I try install nix pkg manager, but have error

bash ./nix-2.29.0-aarch64-linux/install

I tried this as

#!/system/bin/sh
unset LD_PRELOAD
if [ ! -d /nix ]
then
mount -o remount,rw / 
mount -i -o remount,exec,dev /data
mkdir /nix
chmod 755 /nix
fi
mount -o bind /data/local/nix /nix

Then i use login root to login in my entware and start installation script. When i try :debug" script with bash -x, i can't understand where and how work adding this group

nix-on-droid is a wrapper around termux. Under the hood, a proot session started (so that nix-on-droid can read and write to /nix and other directories without root access) and on initial startup nix is installed automatically.

read and write to /nix and other directories

As you can see, i make it with root

initial startup nix

what did you mean? what directly make nix-on-droid if we will don't look at termux and proot - which exactly script do all work?

[Gerschtli]

You can take a look at https://github.com/nix-community/nix-on-droid/blob/master/modules/environment/login/login-inner.nix but if you have root privileges, why don't you just use the nix installer? A lot of this project is just working around the fact, that we do not have root access, not sure what you want to achieve with using nix-on-droid.

nix installer

As you can see - i try this first, it's not working and i start search what i can do with this problem or another way to install nix pkg manager

Not a issue, better suited for discussions, but since you've asked an assortment of questions, here's an assortment of answers.

I just want make "full desktop" system alongside with android

Out of scope for nix-on-droid, but see what the others are doing in #75

and use from second monitor\keyboard\mouse with xserver xdsl and xfce (or another DE).

So out of scope I cannot see it from here. If you actually figure out how to run X or wayland natively under android on a second display, that'd be mighty impressive and I'd love to hear that, but that'd have nothing to do with nix-on-droid.

[./nix-2.29.0-aarch64-linux/install does not work]

Oh, if that worked, I would've never started this project.

Now, back to the project you seem to be not using, not willing to use, but filing issues against nonetheless.

Can you explain mechanism of work this project?

1. You install this project from F-Droid.
2. You run the app.
3. You let the bootstrap do its thing in a proot environment.
4. Now everytime you run the app, you get a bash shell with nix package manager available, with no root, no termux-the-distro and no garbage. Just this project.
5. Inside that proot environment, use nix, not unlike how you'd use it installed on a different non-NixOS linux distro.

Using nix-on-droid?

1. Follow the steps above
2. Become root
3. Execute /data/data/com.termux.nix/files/usr/bin/login (related ticket)

Don't.
