LFS takes the wrong approach in my opinion. I did it once manually over a couple of days. I suppose I hoped enduring the pain of waiting for the packages to compile would somehow make me smarter. It didn’t. I didn’t learn much. It was like following a baking recipe. I know I need to add eggs and sugar in the ratio it says but I’d be damned if I could tell you why that specific ratio works.
It’s just too much to take in at once. You start by building a cross compilation toolchain but… why? And you add the bootloader dead last, even though it’s the first thing you see when you boot a Linux machine?
I reckon a better approach would be to build it step by step, only adding new things once you’ve discovered a need for them. First you get the bootloader working, then you get it to actually load the initramfs and kernel, etc… you could even create your own extremely simple initramfs first before adding dracut, etc…
This gets you to a system you can boot and play with asap. And then you can slowly start to discover why you actually need all these things through exploration and experimentation.

I've learned the most from LFS long time ago, when I had no internet. I had a mismatching set of Slackware and redhat source CDs, and LFS itself didn't match the versions on CDs too. Since then I can build anything and anywhere, even if it's not cooperating :)

As pointed out already, LFS is a cookbook, and you learn most by having an idea about how you want to tune your Linux system.
So at points you want to dive deeper, you do — and go off the beaten path.
It requires a desire not just to understand how bits and pieces fit together, but how you can make them work even better for yourself and what is and is not customizable?
Arguably, even if building it today is easier — back when I did it in 2000, you sometimes struggled to find where the canonical source code of the package is, not to mention compilation errors, linking errors, etc. Only then did you get to configuring the init RC system, choosing between them (no systemd yet), etc.
But a requirement is — IMO — that you are strongly opinionated about how a system should serve you, and look for opportunities to tune it.

LFS is known but it is really more a cookbook than explanatory principles.
Setting up Oasis <https://github.com/oasislinux/oasis> taught me more than LFS personally. Everything being statically compiled makes it less magic.

I learned a lot doing Gentoo stage 1. I was also following the guide like a recipe, but at the time I hadn't been exposed to the underlying machinery that is often automated, abstracted away, or done for me already. It was also a good test on how well I could follow instructions and later on apply my own customisations. Like lego.

I second this a thousand million times. But with AI, i can't help but admit i find myself indulging in building things backwards, now that i can try a couple different approaches simultaneously for it.

FreeBSD’s Makefile system is also in this ballpark

Compiling the packages doesn’t teach much it’s all the glue in between. No? It’s the startup scripts and the configs and creating a kernel and all the things.
It’s on my list of things to do when I have some free time

You know, you could also just read about each step to learn more. I mean if you feel you're following a baking recipe, you can just... read about it more. And then have LFS as a simple way to experiment if you want to change anything or not. Also, technically you don't need to have a bootloader installed on your main hard drive if you already have it on another disk.
I mean, eh... last time I checked, this was Hacker news. Yesterday, there was an Ask HN topic on how to enable dark mode on HN. Is this the new hacker culture? Complaining that the resources merely point in some direction instead of specifying details?

You can tell it's written by real Linux users because the landing page UX doesn't make it immediately obvious where to even start reading.

My journey was: Start off by clicking LFS among the links, and then "Read online" in the sidebar, and then being lost. I see a header, "Current Stable" but I can't see the link to the actual book. I only see the errata, the security advisory and a link labelled... stable LFS systemd? Maybe it's that one? Yes, yes it is.

Took me half a second to realize I would probably start with "LFS :: Linux From Scratch is the main book, the base from which all other projects are derived."

For a long time (probably 2002-2010) I really wanted to do LFS. But I've been on Gentoo since 2004 which, over the last ~22 years, has probably exposed me to almost everything LFS would have, plus a lot more it wouldn't have. I still wish I'd did it way back when. I probably would stumbled through fewer issues had I.

This whole project wastes time that could be spent learning operating system design and it spends it telling users to download files and run ./configure; make; make install 100 times.

I did LFS once, a long long time ago (days of RedHat 7.3, I'd say, 2002), and it was quite educational! It's a good way to learn the fundamentals of what comprises an actual Linux system
LFS is really, really bad. Also, reading the Linux kernel documentation to understand how to do it right is infuriating because it too is really, really bad.
