## Fase 2: Chroot
This part is significantly less over engineerd (luckily).
There are 4 commands the user should be aware of, they are writen in chronological order.

There are 4 new commands the user should be aware of, they are written in chronological order.
* chroot_prepare_iglunix
This creates the chroot and cleans the most important locations (/lib, /bin, /sbin, /usr, /iglunix, /etc).
It will also copy the network and keyboard configuration from the host. This will be put into the `*.img`by a script hosted in iglunix/iglunix.
* chroot_fetch

## Trivia
Everything in trivia is not important.
* The name `Iglunix`
This comes from the following reasoning, by yours truly aheirman.
```
∄GNU --> iglu
iglu-unix --> iglunix
```
* The location to place the git repository of `iglunix` in the filesystem is controversial. These are the contenders:
```
/iglunix
/root/iglunix
```
The `iglunix` repo tries to be agnostic to the install dir. This repo choses (because it must choose) for `/root/iglunix`.
