Make Arch Linux images on Fedora Rawhide using Systemd Mkosi

Step 1

Install mkosi and arch-install-scripts on your Fedora Rawhide installation.

$ sudo dnf install mkosi arch-install-scripts

Step 2

Initialize the client GPG key for the pacman package manager and populate the official repositories for archlinuxarm.

$ sudo pacman-key --init

$ sudo pacman-key --populate archlinux

Step 3

Create a directory for building the Arch Linux OS image and make it the present working directory.

$ mkdir archgrid

$ cd archgrid

Step 4

Configure the OS image specification using the text editor of your choice.

$ nano mkosi.conf

Step 5

Start building the operating system image by executing the following command.

$ sudo mkosi build

mkosi-multarch.md

Building OS images for multiple architecures

Step 1

sudo dnf install qemu --setopt=install_weak_deps=False

Step 2

sudo dnf install qemu-user-static --setopt=install_weak_deps=False

Step 3

nano mkosi.conf

Step 4

sudo mkosi build

Step 5

Copy over the image to a Raspberry Pi device running aarch64-based operating system and set up symbolic link

In the Raspberry Pi device

ln -sf fedogrid_0.1.2.raw fedogrid

Step 6

In the Raspberry Pi device

sudo machinectl import-raw fedogrid

Step 7

In the Raspberry Pi device

sudo machinectl start fedogrid

Step 8

In the Raspberry Pi device

sudo machinectl shell fedogrid

using-lorax.txt

1. Download the fedora-minimal kickstart file

```
wget https://github.com/weldr/lorax/raw/master/docs/fedora-minimal.ks
```

2. Disable the SELinux first

```
setenforce 0
```

3. Create an Anaconda boot ISO

```
sudo \
  lorax \
  --product Fedora \
  --version 38 \
  --release 38 \
  --source http://dl.fedoraproject.org/pub/fedora/linux/releases/38/Everything/x86_64/os/ \
  rslt/
```

4. Make the resulting directory as the present working directory of the livemedia generation.

```
cd rslt/
```

5. Create a live media from the generated ISO with logs being displayed on 0 port offset from the default VNC port (i.e. 5900)

```
sudo \
  livemedia-creator \
  --make-iso \
  --iso=/path/to/the/generated/anaconda/boot/ISO/in/previous/step \
  --ks=fedora-minimal.ks
  
sudo \
  livemedia-creator \
  --make-iso \
  --iso=rslt/images/boot.iso \
  --ks=fedora-minimal.ks \
  --vnc=vnc=0.0.0.0:0 \
  --virt-uefi
```

6. Re-enable the SELinux after completion

```
setenforce 1
```
