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 https://felixc.at/vps2arch
|
|
chmod +x vps2arch
|
|
./vps2arch
|
|
|
|
Some _Debian_ _VPS_ images don't have the _CA certificates_ installed, so `wget` will give you the following errors:
|
|
|
|
ERROR: The certificate of `gitlab.com' is not trusted.
|
|
ERROR: The certificate of `gitlab.com' hasn't got a known issuer.
|
|
|
|
To fix them just execute `apt-get install ca-certificates` and then re-execute the previous commands.
|
|
|
|
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: using `ld.so` from the _Bootstrap chroot_ to launch the `chroot` tool.
|
|
|
|
Since it will erase all the system directories except from the _Bootstrap chroot_, `/dev`, `/proc`, `/sys` and the like,
|
|
the only way to launch a command inside the _Bootstrap chroot_ is to using ld.so from the _Bootstrap chroot_ itself.
|
|
|
|
At this point _Arch Linux_ has been installed, but not configured.
|
|
The script will provide a SSH-able system automagically configuring grub (or syslinux), network and restoring the root password from the original system (or by using `vps2arch` as password if no root password was set).
|
|
|
|
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!
|
|
|
|
On the [Tested VPS Providers](https://gitlab.com/drizzt/vps2arch/wikis/Tested-VPS-Providers) wiki page you can find a list of **Tested VPS Providers**.
|
|
|
|
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
|
|
-------
|
|
|
|
_IPv6_ currently is not supported. If you need to use it, please configure it manually.
