# Arch Linux Installer
|
||||
|
||||
## Running the installer
|
||||
|
||||
### Via ssh and custom livemedium
|
||||
|
||||
1) Build custom [archiso](https://gitlab.archlinux.org/archlinux/archiso) live medium using docker in privileged mode:
|
||||
|
||||
```shell
|
||||
# dependencies: docker, docker-compose
|
||||
|
||||
cd build-iso
|
||||
# sudo systemctl start docker
|
||||
sudo docker-compose run archiso
|
||||
ls out/out_dir/*.iso
|
||||
```
|
||||
|
||||
**On the target computer:**
|
||||
|
||||
2) Boot into the live medium
|
||||
3) Connect to the Internet
|
||||
* [wifi instructions](https://wiki.archlinux.org/title/Iwd#iwctl)
|
||||
|
||||
**On some other computer:**
|
||||
|
||||
4) Connect to target computer via `ssh`
|
||||
* See [build-iso/out/out_dir/ssh-host-fingerprints](../../build-iso/out/out_dir/ssh-host-fingerprints)
|
||||
for verification of the ssh fingerprint of the target computer
|
||||
5) (Optional) Copy and adjust one of the example configurations (`/etc/de-p1st-installer/*.cfg`) to `/etc/de-p1st-installer/installer.cfg`
|
||||
* If this step is skipped, then (most) of the configuration can be entered interactively
|
||||
* TODO: if `ADDITIONAL_PKGS` is empty, interactively ask for it.
|
||||
6) Run the installer:
|
||||
|
||||
```shell
|
||||
de-p1st-installer
|
||||
```
|
||||
|
||||
### Via official livemedium
|
||||
|
||||
1) Boot into [official live medium](https://archlinux.org/download/)
|
||||
2) Add to `/etc/pacman.conf`:
|
||||
|
||||
```shell
|
||||
[de-p1st]
|
||||
SigLevel = Optional TrustAll
|
||||
Server = https://arch.p1st.de
|
||||
```
|
||||
|
||||
3) (Optional) Install screen with a `screenrc` configuration file for long scrollback history
|
||||
|
||||
```shell
|
||||
pacman -Sy
|
||||
pacman -S de-p1st-screen
|
||||
|
||||
# And then start it with:
|
||||
screen
|
||||
```
|
||||
|
||||
4) Install `de-p1st-installer` to get the install script
|
||||
|
||||
```shell
|
||||
pacman -Sy
|
||||
pacman -S de-p1st-installer
|
||||
```
|
||||
|
||||
5) Continue with step (5) of "Via custom livemedium"
