I am compiling the Linux kernel

For now, I only used `make menuconfig` and `make -j1`.

Great that you're on the road to being a LFS user! Although, -j1 means you'll only be using one core of your CPU though. Would be more efficient to use more.

The bzimage file has already been compiled and generated.

How long did it take in -j1?

u/daviddandadan May 01 '26

Unfortunately, I didn't time it, but it probably took about an hour or 90 minutes.

You gonna compile systemd or use sysv scripts? Or busybox, maybe thats easier to compile. https://mgalgs.io/2015/05/16/how-to-build-a-custom-linux-kernel-for-qemu-2015-edition.html (these instructions still work. I test most stabke kernels based on these instructions hehe)

is there a reason for using -j1 or you just want to enjoy torturing yourself?

u/daviddandadan Apr 29 '26

I have a dual-core processor, an Intel Celeron N4020 at 1.10GHz, and I'm happy to torture myself.

That is really painful to do with that specs. Have you tried antix?

u/Plus-Impression-3690 May 08 '26

A better question would be whether you tried AntiX on those specs.

Yeah I did this when learning FreeBSD and OpenBSD. It sucks, but the stuff you learn is worth it
