VPS2Arch

The fastest way to convert a VPS to Arch Linux!

Author

Timothy Redaelli

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.

Disclaimer

I'm not responsible for any damage in your system and/or any violation of the agreement between you and your vps provider.
Use at your own risk!

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), 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 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.

Contributing

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.

vps2arch's Issues

Not working on Openvz

I have just tried it on openvz(woiden.id)，it just didnt work...The vps didnt boot...

Inherit ssh_host__key from the original distribution

在一些不提供 arch 镜像/模板的 idc 有可能连 vnc 也不提供，这导致 vps2arch 后不能方便地确认新的 sshkey
我建议在安装 arch 时把原发行版上生成好的 sshkey 备份到一个地方，安装后启用 sshd 之前把 sshkey 放进 /etc/ssh 里

systemd errors

systemd-logind.service: Failed to connect stdout to the journal socket, ignoring: No such file or directory
Failed to mount /run/systemd/inaccessible/sock to /run/systemd/unit-root/dev/kmsg: No such file or directory
systemd-logind.service: Failed to set up mount namespacing: /run/systemd/unit-root/dev/kmsg: No such file or directory
systemd-logind.service: Failed to step NAMESPACE spawning /usr/lib/systemd/systemd-logind: No such file or directory

// Repeat the above output 4 more times

systemd-recolved.service: Failed to determine user credentials: No such process
systemd-recolved.service: Failed at step USER spawning /lib/systemd/systemd-resolved: No such process

There may be more errors, these are the two I can see.

Then if I execute a reboot:

System has not been booted with systemd as init system(PID 1). Can't operate.
Failed to connect to bus: Host is down
System has not been booted with systemd as init system(PID 1). Can't operate.
Failed to connect to bus: Host is down
Failed to talk to init daemon: Host is down

Reproduced on a Cloud VPS and a VBox virtual machine.

How to config IPv6 manually

In README it says 'IPv6 currently is not supported. If you need to use it, please configure it manually'. But it does not mention the way to config it manually.

about ipv6

May I ask how to use this script for vps in only ipv6 environment

Is working at Oracle Always Free

It worked without problems here on my Oracle VPS I just needed to run the script with root

Failure caused by Multiple Errors

我在VMware中安装了Debian并以Root身份执行了vps2arch2，但发生了以下的错误：

Great script and succeeded on both my local Virtualbox VM and cloud box. But my uxrvt terminal consistently receives warning when run some specific systemctl commands:

Add option to specify the country of the mirrors to run reflector

Running reflector for a list of mirrors around the world is slow. Better to have an option to specify a country code and only run reflector on the mirrors in that particular country. I know there is an "-m" option to specify a single mirror, but that is not as easy to use as to just type a country code.
