Creates a Rocky Linux usb drive that will boot on Apple M-series systems

**This image was built on a Fedora aarch64 system

Fedora Package Install
dnf install arch-install-scripts bubblewrap gdisk mkosi pandoc rsync systemd-container

Notes

• The root password is rocky
• The qemu-user-static package is needed if building the image on a non-aarch64 system
  -This project will work with mkosi versions less then or equal to mkosi v23 If needed, you can always install a specific version via pip python3 -m pip install --user git+https://github.com/systemd/mkosi.git@v23

To build a minimal Rocky Linux image and install it to a usb drive, simply run:

./build.sh -d /dev/sda

note: substitute /dev/sda with the device id of your usb drive

If you've previously installed this Rocky Linux image to the usb drive, you can wipe the drive and install a new image without having to repartition/reformat the drive by providing the -w argument

./build.sh -wd /dev/sda

Once the drive is created, you can locally mount, unmount, or chroot into the usb drive (which contains 3 partitions) to/from mnt_usb/ with

./build.sh mount
./build.sh umount
./build.sh chroot

note: mounting the usb drive is useful for inspecting the contents of the drive or making changes to it

To boot the usb drive on an apple silicon system:

Boot to Asahi Linux on the internal drive and add the usb drive to the grub menu

[root@m1 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg 
Generating grub configuration file ...
Found Fedora Linux Asahi Remix 42 (Forty Two [Adams]) on /dev/nvme0n1p7
Found Rocky Linux 9.6 (Blue Onyx) on /dev/sda3

You should now see the /dev/sda3 entry in the main grub menu
If you don't see the grub menu at all or if the text is garbled, then ensure these options are set in /etc/default/grub and then run grub2-mkconfig -o /boot/grub2/grub.cfg on the internal drive

GRUB_TIMEOUT_STYLE="menu"
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_FONT=/boot/grub2/fonts/unicode.pf2

Setting up WiFi

To connect to a wireless network, use the following sytanx: nmcli dev wifi connect network-ssid

An actual example: nmcli dev wifi connect blacknet-ac password supersecretpassword
