Not really, no. Free software doesn't mean someone isn't working for free.

I did not say that you are supposed to use it. I linked one of the many online
tutorials available which explain a way to build your own kernel. There are
many tutorials out there. If you prefer a different way, I would be the last
one to tell you otherwise.

Building your kernel is a extremely ubiquitous and common topic. I don't
want to brag, but I have already done that when I was 15 or 16 when I
installed SUSE Linux 5.3 for the first time. Again, it's a handful of

Again, a) a lot documentation for building a kernel already exists, b)
we don't have the manpower to do any hand-holding. For professional
products like enterprise distributions, companies actually have dedicated
doc teams, at least SUSE does.

I suggest then that you post the particular error message you are seeing. That's
much easier for me than writing a 50-page documentation which spoon-feeds the

Without anyone reimbursing me for that. It's not that my time is free.

Again, the documentation already exists.

The process of building a RISC-V kernel isn't any different from building a
PowerPC kernel.

Then feel free to write a super long and extensive document which spoonfeeds users
the process to build and install a Linux kernel from source to be run on a Apple
PowerMac G5 running Debian PowerPC unstable.
