Preparing Image

[MRIIOT]

After imaging a Pi with say 5.15.32, can one run apt dist-upgrade before or after patching, or does it not matter?

I dont' use apt dist-upgrade, so I'm not sure, but I don't think it matters.

When you install an additional kernel from deb package using the instructions in this repo's wiki, the installed kernel is independent of any other installed kernels. It won't be replaced by apt dist-upgrade.

Which kernel is actually used to boot is set in /boot/config.txt. My installation procedure adds a section to /boot/config.txt, which if enabled, boots to that kernel. Multiple kernels can be installed, and it will boot to the kernel whose section is enabled. If no section is enabled, it will boot to the default kernel.

I believe that apt dist-upgrade will replace the default kernel. But default kernel will not be used if /boot/config.txt has a section enabled which forces boot to a different kernel.
