asahi-centosstream-builder

Builds a minimal CentOS Stream 9 image to run on Apple M1 systems. Kudos to Leif Liddy and Asahi community for helping make this happen.

This is completely unofficial and on a best-effort basis. It's for personal usage, but if you'd like to use it and contribute great.

package install for building images

dnf install mkosi arch-install-scripts systemd-container zip qemu-user-static

note: qemu-user-static is not needed if building the image on an aarch64 system.

note: at present building the arch-install-scripts rpm is only available on fedora 35/36

To install a prebuilt image

Make sure to update your macOS to version 12.3 or later, then just pull up a Terminal in macOS and paste in this command:

curl https://ecurtin.fedorapeople.org/centos.sh | sh

Notes:

  1. The root password is centosstream

  2. On the first boot the asahi-firstboot.service will run and will take around 45 seconds to complete.
    Do not shutdown or reboot the system before this service has completed.

  3. The Asahi Linux-related RPM's (and Source RPM's) used in this image can be found here:
    https://ecurtin.fedorapeople.org/asahi-linux/9-stream/ All RPM's signed are signed by a GPG key.
    The repo config can be found here:
    https://ecurtin.fedorapeople.org/asahi-linux/asahi-linux.repo

  4. The CentOS Stream kernel config used is nearly identical to the kernel config used by the Asahi Linux project (a few CentOS Stream specific modifications were made):

    https://github.com/AsahiLinux/PKGBUILDs/blob/main/linux-asahi/config

  5. systemd-networkd is the sole network service that's installed in this image.
    Basic config files for the eth0 and wlp1s0f0 interfaces are included in the image
    ie.
    /etc/systemd/network/eth0.network

    [Match]
Name=eth0

[Network]
DHCP=yes

    The eth0 interface is what an external usb ethernet adapter "should" be assigned to.

  6. Use iwd to setup the wifi interface (see info below)

Wiping Linux

Bring up a Terminal in macOS and run the following Asahi Linux script:
curl -L https://alx.sh/wipe-linux | sh
You should definitely understand what this script does before running it.
