# archinstall
Just a bare bone automated [Arch](https://wiki.archlinux.org/index.php/Arch_Linux) install with optional network deployment instructions based on MAC-address.
Pre-built ISO's can be found here: https://hvornum.se/archiso/
# Install a basic Arch Linux
In a live-cd environment, do:
# wget https://raw.githubusercontent.com/Torxed/archinstall/master/archinstall.py
# pacman -S --noconfirm python; python archinstall.py --default
This will install a basic Arch Linux, without interaction, on the first drive it finds *(after user confirms it)*.<br>
Use `--drive=/dev/sdb` etc to change the desired destination, or skip `--default` if you want to get options for your installation.
> NOTE: Follow [ArchISO](https://wiki.archlinux.org/index.php/archiso)'s guide on how to create your own ISO or use a pre-built [guided ISO](https://hvornum.se/archiso/) to skip the python installation step, or to create auto-installing ISO templates. Below is examples and a cheat sheet on how to create such a ISO *(with different flavors)*.
# Features
* Unattended install of Arch Linux
* User guided install of Arch Linux (Like most other distros have)
* YubiKey support for disk and root password (next release)
* Profile / Template based installs
* Supports offline-installation of Arch Linux
* Full disk encryption, locale/region settings and customizable application selection
* Never creates post-install/service scripts (usually used to finalize databases etc)
# Autorun on Arch Live CD (Unattended install)
This guides you on how to create a ISO that has Python and can run the arch installed in **unattended mode.**<br>
We'll need to reconfigure the **releng** profile after it's been copied, to include Python etc.<br>
To do so, we need to add some packages to `packages.x86_64` and add some commands to `customize_airootfs.sh`.
# cd ~/archlive
# echo -e "git\npython\npython-psutil" >> packages.x86_64
# cat <<EOF >> ./airootfs/root/customize_airootfs.sh
cd /root
git clone https://github.com/Torxed/archinstall.git
chmod +x ~/archinstall/archinstall.py
EOF
# mkdir ./airootfs/etc/skel
# echo '[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && sh -c "~/archinstall/archinstall.py --default"' >> ./airootfs/etc/skel/.zprofile
> Note: `~/archlive` might be different on your system, see [ArchISO#Setup](https://wiki.archlinux.org/index.php/archiso#Setup) for more info.
After all those commands are done, you can go ahead and run:
# rm -v work*; ./build.sh -v
Whenever this live-cd boots, from here on now - it'll run `archinstall.py` and attempt to unattendely install a default Arch Linux base OS with `base base-devel` as packages.
Or - if successfull - a MAC-address matches a profile at [/deployments](https://github.com/Torxed/archinstall/tree/master/deployments) for the machine to be installed.
> **CAUTION**: If no parameters are given, **it will devour the first disk in your system** (Usually `/dev/sda`, `/dev/nvme0n1` etc).
## Unattended profile install
Everything in the steps above are the same, except for one line that needs to change to look like this:
# echo '[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && sh -c "~/archinstall/archinstall.py --profile=workstation"' >> ./airootfs/etc/skel/.zprofile
This will unattendely install the [workstation](https://github.com/Torxed/archinstall/blob/master/deployments/workstation.json) profile.
## User guided installation (DEFAULT)
Change the autostart line to match:
# echo '[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && sh -c "~/archinstall/archinstall.py"' >> ./airootfs/etc/skel/.zprofile
This will cause the script to halt and ask for a profile to install before proceeding.
When asked, enter `workstation` for instance - to install based on the [workstation](https://github.com/Torxed/archinstall/blob/master/deployments/workstation.json) template.
> **CAUTION**: If a MAC-address matches under `/deployments`, that profile will forcefully be installed and have presidence over any other profile information.
## With custom webserver for deployment profiles
Again, one line differs from the other install methods, change the following line:
# echo '[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && sh -c "~/archinstall/archinstall.py --profiles-path=http://example.com/profiles"' >> ./airootfs/etc/skel/.zprofile
This will cause the script to look at `http://example.com/profiles/<profile>.json` for instructions.
# Rerunning a installation
# umount -R /mnt; cryptsetup close /dev/mapper/luksdev
# python3 ./archinstall/archinstall.py
> Note: This assumes `--post=stay` is set to avoid instant reboot at the end or if during any time a user pressed `Ctrl-C` and aborted the installation.
# Some parameters you can give it
--drive=</dev/sdX>
Which drive to install arch on, if absent, the first disk under /dev/ is used
--size=100% (Default)
Sets the size of the root filesystem (btrfs)
--start=513MiB (Default)
Sets the starting location of the root partition
(TODO: /boot will take up space from 1MiB - <start>, make sure boot is no larger than 513MiB)
--password=0000 (Default)
Which disk password to use,
--password="<STDIN>" for prompt of password
--password="<YUBIKEY>" for setting a unique password on the YubiKey and use that as a password
(NOTE: This will wipe/replace slot 1 on the YubiKey)
--pwfile=/tmp/diskpw (Default)
Which file to store the disk encryption password while sending it to cryptsetup
--hostname=Arcinstall (Default)
Sets the hostname of the box
--country=SE (Default)
Default mirror allocation for fetching packages.
--packages='' (Default)
Which additional packages to install, defaults to none.
(Space separated as it's passed unchanged to `pacstrap`
--user=<name>
Adds an additional username to the system (default group Wheel)
--post=reboot (Default)
After a successful install, reboots into the system. Use --post=stay to not reboot.
--default
This parameter causes the installation script to install arch unattended on the first disk
--profile=<name>
For instance, --profile=workstation will install the workstation profile.
--profiles-path=https://example.com/profiles
Changes the default path the script looks for deployment profiles.
The default path is 'https://raw.githubusercontent.com/Torxed/archinstall/master/deployments'
Deployment profile structs support all the above parameters and more, for instance, custom arguments with string formatting.
See [deployments/workstation.json](https://github.com/Torxed/archinstall/blob/net-deploy/deployments/workstation.json) for examples.
