I followed Mental Outlaw's 2019 guide and followed the official handbook to get up-to-date instructions and tailored instructions for my system, the process took about 4 hours however I did go out for a nice walk while my kernel was compiling. Overall I enjoyed the process and learnt a lot about the Linux kernel while doing it.
I'm planning on installing it to my hardware soon, this was to get a feel for the process in a non-destructive way.
Agreed. It's such a great learning process. I ultimately gave up on Gentoo but learned a lot by using it for about 2 years way back in around 2005.
Linux From Scratch brings a huge leap in understanding too.
I found Gentoo more helpful than LFS because with LFS you compile about 80 packages from source one at a time but you don't learn too much about the packages.
LFS gave me much more awareness of what packages actually come with a Linux install but Gentoo taught me more about configuring and booting a Linux system.
Although I'd definitely recommend both to anyone wanting to learn. I'd do Gentoo first then LFS.
Edit: LFS is also a masterclass in cross compiling so if that's something you're curious about LFS is the way to go.
Back in like 2011 I was living out of state for college. Had decided to drop out at the time so had limitless free time for a bit. I definitely used that time to compile my own kernel and setup gentoo lol. I haven’t played with gentoo since but it was fun and helped my appreciation for Linux.
Linux from Scratch is also an immensely powerful tool for deployment of secure software. Rebuilding the entire infrastructure between releases ensures threat actors can’t stay resident for long if the compromise production systems.
I installed LFS that on my Dell Latitude 13 (Core 2 Duo SU7300) in a 3 month on and off operation, with packages compiling (and failing) overnight all the time.
