Description
|
|
-----------
|
|
|
|
This script is used to convert a _VPS_, running another linux distro, to _Arch Linux_.
|
|
It should be **only** used if your _VPS_ provider doesn't provide you an _Arch Linux_ image.

|
How To
|
|
------
|
|
|
|
Download the script on your _VPS_ and execute it with root privileges
|
|
|
|
**WARNING** The script will **delete** any data in your _VPS_!
|
|
|
|
wget http://git.io/vps2arch
|
|
chmod +x vps2arch
|
|
./vps2arch
|
|
|
|
How does it work?
|
|
-----------------
|
|
|
|
It's Black Magic.
|
|
Just kiddin' 😏, the script itself is very simple.
|
|
|
|
In a nutshell, it will download the _Arch Linux Bootstrap Image_ and (see the [wiki](https://wiki.archlinux.org/index.php/Install_from_existing_Linux#Method_B:_Using_the_Bootstrap_Image_.28recommended.29)),
|
|
extract the image to / and configure the _Bootstrap chroot_.
|
|
|
|
Now, about the **critical** part:
|
|
|
|
> How can you wipe the system without breaking everything?
|
|
|
|
It's simple: the script downloads and installs [busybox](http://www.busybox.net/) in the _Bootstrap chroot_.
|
|
|
|
After that, it will erase all the system directories except from the _Bootstrap chroot_, `/dev`, `/proc`, `/sys` and the like .
|
|
|
|
Busybox is statically linked, so it can still be used to chroot to the _Bootstrap chroot_ and to install _Arch Linux_.
|
|
|
|
At this point _Arch Linux_ has been installed, but not configured.
|
|
The script will provide a SSH-able system automagically configuring grub, network and restoring the root password from the original system.
|
|
|
|
Once done doing its job, the script will ask you to manually reboot your _VPS_ and voilà, PROFIT!
|
|
|
|
Does it really work?
|
|
--------------------
|
|
|
|
Yes, it does!
|
|
|
|
For the time being, the script has been tested on the following linux distros:
|
|
|
|
* CentOS 6 (x86 and x86_64)
|
|
* CentOS 7 (x86 and x86_64)
|
|
|
|
on the following _VPS_ providers:
|
|
|
|
* [CloudAtCost](http://www.cloudatcost.com/)
|
|
|
|
Theoretically it should also work on **real** computers (running linux), but I think it's not worth it,
|
|
because you can install it in the canonical way.

If you have any useful modification, please use **Pull requests**.
|
|
If you have successfully used this script on a different _distro_ - _VPS_ combination, please contact me so that I can update the above list.
|
|
|
|
If you are not a developer, but you still want to contribute, you can donate me an account on your _VPS_ provider and I'll do my best to support it.
|
|
Or you can just donate me some bucks I'll spend to buy a _VPS_ on your provider in order to support it.

Caveats
|
|
-------
|
|
|
|
[OpenVZ](http://openvz.org/), [Virtuozzo](http://www.odin.com/products/virtuozzo/), [Docker](https://www.docker.com/) or any other similar _VPS_ systems are not supported (for the time being).
|
|
|
|
In other words, it'll only work on **fully virtualized** systems.
