# Linux for cloning

## About
`images/linux` is Debian 10 system adapted for network booting and sending/receiving disk images via UDP. It is designed to work together with `images/server`.

On boot, full system image will be downloaded, mounted read only and will become new root (see `src/etc/initramfs-tools`). User will be presented with menu allowing sending/receiving images and root shell access (see `src/scripts`). Whole environment will be read-only, except `/tmp` where writeable `tmpfs` will be mounted.

## Installation
To build just run:
```
sudo make
```
This will download base system to `build/cache`, copy it to `build/rootfs` and continue build there. After successful completion of this command, a fully functional linux root filesystem will be present in `build/rootfs`.

`debootstrap` is required to download base Linux system. When more advanced (encrypted home etc.) partition setup is used, one might need to remount the partition on which the build is taking place with `exec` and `dev` before running `make`:
```
sudo mount -i -o remount,exec,dev /home/whatever
```
