I need to make some minor modifications to the kernel, but want to run PureOS. What's the easiest way to do that?

Good question, I too would like to know the answer.

For Librem 5 there is this thread:

Librem 5 kernel hacking

I would like to learn how things work regarding the Linux kernel on the Librem 5, how to modify and rebuild the kernel, how to install a modified version and how to choose which kernel gets used in case several versions are installed. Things like that. Here is what I figured out so far. We can get the kernel source code from the git repo at https://source.puri.sm/Librem5/linux-next like this: sudo apt install git git clone https://source.puri.sm/Librem5/linux-next.git That takes a while, it’…

For x86_64 I suppose it should work in the same way, except I don’t know where to get the source code in that case. (For the Librem 5 the kernel source code is here: Librem5 / linux · GitLab)

As far as I can tell, the PureOS repos at PureOS · GitLab do not include the kernel which I think means that PureOS uses some standard Debian kernel for which we should be able to get the source code from Debian somehow. But I don’t know how. Of course there is the mainline kernel source code from kernel.org but that does not tell us anything about the configuration used for PureOS and how to make it a deb package of a kind that would work for PureOS.

On my Librem 14, under /boot/ there are files called “config-” with different version numbers that contain kernel configuration options, so that’s something.
