Getting LinuxCNC as an option to RPi Imager

Raspberry Pi Imager is a user-friendly software by Raspberry Pi Foundation for writing an operating system image to an SD card of Raspberry Pi or eMMC of a Compute Module. The interface includes a step where an image can be selected, and the selection includes third party operating systems as well. Getting LinuxCNC included in this list might help to raise awareness of the fact that LinuxCNC can run on RPi and of the project in general. Also, this can be the preferred and the easiest way of installing the OS for users who are not comfortable using the command line.

To submit LinuxCNC for inclusion, we need to host ready to use RPi images, 40x40 pixel icon and some JSON ( example submission ). When it's all accessible with direct links, someone should fill the form , and wait for approval.

I asked the RPi foundation about this a few years ago, and they said that they were trying to reduce the number of special purpose installations, rather than increase them.
That policy might have changed in the meantime.

"Andy

Thank you for your interest in Raspberry Pi.

We're currently not adding many external OSes to the Imager, but please add your suggestion to the github issues and we'll decide what we do about third party OSes. github.com/raspberrypi/rpi-imager/issues

Regards"

Two things have changed in the interim:
1) LinuxCNC is now in Debian
2) preempt-rt is in mainline Linux.
