I successfully installed Gentoo for the first time today!

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.
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.
I had considered trying it at one point. Unfortunately one specific user on discord kept telling me to install it to the point of dming me "gentoo" almost every day, at which point I blocked them and vowed never to install gentoo
I use Arch on my host machine, the stuff I learnt when doing Gentoo today was wayyy deeper than Arch has ever gotten near. I agree that Arch teaches what most people should know, but Gentoo fully teaches what most people should have at least a small understanding of.
