HPR4299: Building your own Debian images for your Raspberry Pi
Hosted by dnt on 2025-01-23 00:00:00This show has been flagged as Clean by the host.
On https://raspi.debian.net/ one time the image was broken, so I had to built it myself.
https://salsa.debian.org/raspi-team/image-specs
The makefile can create you a yaml file for your pi model and your release of Debian. Then you can edit that file to do whatever you want to the system, before making it into an image.
For example:
- In the section apt/packages, add sudo.
- Create a user, add it to the sudo group, with password "" and /bin/bash for shell
- Create a .ssh for your user, and echo in your SSH public keyboard
That way you can boot into your new Debian system without having to have a screen.
As soon as you login, the first thing you should do is reset your own password.
By doing -p "" we set the password to empty.
If we had not done -p "" the password would have been empty but locked, so you wouldn't be able to sudo.
Also go ahead and lock your root user password, which you could also do from the file.
Build your image, and go.

Hi dnt,
I didn't know that, thank you for the show.
Question, as far as I know RPI still has a Firmware blob. Do you get this via Debian?
Cheers

Hey, Reto!
I believe so, there is a debian package called raspi-firmware. See https://salsa.debian.org/raspi-team/image-specs/-/blob/master/raspi_master.yaml?ref_type=heads#L83
Sidenote: since recording this, I've learned that the graphical app Raspberry Pi Imager (https://www.raspberrypi.com/news/raspberry-pi-imager-imaging-utility/) can do some of the things I talked about here, such as adding an ssh key to the authorized_keys file.
