Introduction

This is my very first public rust project for fun purposes.

Obviously this was written in Rust - a systems programming language by a noob rustacean with a few hours of experience with rust 😝

My code may seem funny in some parts since I've just tried to apply what I've learnt so far apart from the better ways of doing such tasks

So, kindly ignore as long I'm a noob LoL

Build instructions

• First of all you need rust. Follow the link below and you will know what to do.

It'll also autoinstall rustc and cargo for you.

https://www.rust-lang.org/tools/install

• Once you have rust and everything it brings, we add a new target. Run the following command:

rustup target add x86_64-unknown-linux-musl

Or if you wan to make for 32bit arch then the target should be i686-unknown-linux-musl.

• After you have the build targets installed simply run the following command:

RUSTFLAGS='-C link-arg=-s' cargo build --release --target x86_64-unknown-linux-musl  # For 64bit

# or

RUSTFLAGS='-C link-arg=-s' cargo build --release --target i686-unknown-linux-musl    # For 32bit

Then you should find the output as target/x86_64-unknown-linux-musl/release/rusty-magisk (64bit)

Installation

For Android-9 and below

• Copy your ramdisk.img and the rusty-magisk binary in an ext4 partition directory and run the following commands:

su
mkdir ramdisk && ( cd ramdisk && zcat ../ramdisk.img | cpio -iud && mv init init.real )
rsync rusty-magisk ramdisk/init && chmod 777 ramdisk/init && ( cd ramdisk && find . | cpio -o -H newc | gzip > ../ramdisk.img )

Tl;dr: In short, you need to rename init executable to init.real and put rusty-magisk as init inside your ramdisk.img.

For Android-10 and above

• If your system image is system.sfs then you need to extract it, an quick way to do that is: 7z x system.sfs && rm system.sfs

• Once you have system.img you need to mount it: mkdir mdir && sudo mount -o loop system.img mdir

• Now rename init to init.real by running the following command: sudo mv mdir/init mdir/init.real

• Lastly put rusty-magisk binary as init executable at / of system.img: sudo rsync rusty-magisk mdir/init && chmod 777 mdir/init

Note

I'm assuming that you have rusty-magisk binary at the same dir as your android-x86 OS files.

Quick-tip: You can also get pre-built rusty-magisk binaries at https://github.com/AXIM0S/rusty-magisk/releases : Rusty-Magisk can be easily installed from GearLock.
