Re: Installing/Preparing Debian on a headless system

Hello,
after learning that the Debian-based RaspberryPi OS does not get
security fixes always in time (see dirty-pipe), I am considering
installing pure Debian on my system. It seems not all proprietary
components are supported, but I don't need video acceleration anyway,
for example. My Pi acts as a home server.
The thing is, the Pi is headless, it was never connected to a monitor or
keyboard, all configuration was done via SSH on a pre-built Raspberry PI
OS image. I do not even have an USB keyboard and the Pi has obviously no
PS/2 connectors.
Do you have some ideas for me, how I could prepare a minimal Debian
image on my notebook which is able to boot on the Pi and has already an
user and SSH configured? Everything else I would setup remotely.
There is someone who does prebuilt pure debian images that will get you
started.

Hi,
Many thanks for your debian images for the raspberry pi. They solved
my
confusion after I tried to do this myself and failed miserably.
I am very happy that my work is useful to you!
One tiny change I'd quite like you to consider is either an
authorized_keys file for root where you publish the private key or a
root password set rather than empty so that you can login using ssh on
an initial boot.
Take a look at /boot/firmware/sysconf.txt (that is, /sysconf.txt in
the firmware partition, the partition formatted with vfat). It has:
# root_authorized_key - Set an authorized key for a root ssh login
#root_authorized_key=
Greetings!
