Steps to rebuild RPI image

[febus982]

Related to: #8592

I want to alter

talos/pkg/minimal/limits.go

Line 21 in 78bc3a4

minimum = 2*humanize.GiByte - 150*humanize.MiByte

) and rebuild the relevant packages myself to run on a RPI .

I looked into these 2 guides:

• https://www.talos.dev/v1.6/advanced/developing-talos/
• https://www.talos.dev/v1.6/advanced/building-images/

I managed to run the make targets in the guides however for raspberry PIs I found a specific target in the Makefile (make sbc-rpi_generic).

Running it returns an error:

make sbc-rpi_generic IMAGE_REGISTRY=127.0.0.1:5005 PUSH=true
v1.6.7-dirty: Pulling from siderolabs/imager
no matching manifest for linux/arm64/v8 in the manifest list entries

Questions:

• Exactly what components I should rebuild when altering the memory check? (e.g. I need only to rebuild the installer docker image? Do I need to rebuild talosctl?)
• What is the exact list of make target and options to build such components?

I think this might do the trick (please correct if wrong):

export IMAGE_REGISTRY=127.0.0.1:5005
export PUSH=true
export PLATFORM=linux/arm64
export INSTALLER_ARCH=arm64

make installer
make imager
make image-rpi_generic

I need only to test this in a linux machine. Mac OS doesn't provide the loopback device in /dev/loop and the last step throws an error🤦‍♂️

It works 👍
