LFS standards

My inner irritating perfectionist is coming out, and I'm leaning towards this being unnecessary, but how many of you went through ALL the primary standards LFS follows before starting this project?

Reading the documentation for these standards feels like a whole project on their own.

Let me rephrase my question:

I'm about to start Linux From Scratch, and I'm wondering how many people actually read through the primary standards (POSIX, FHS, etc.) before beginning.

The standards documentation is massive, and reading all of it feels like a project in itself. Did you study these specifications in depth first, or is a general understanding enough while working through the book?

Customized LFS ext4 with OpenRC, COSMIC, and KDE Plasma

alrighty here is a better breakdown of what I got going on.I apologize for the other posts I deleted them and consolidated this all into one post with better screenshots :)

I also finally got around to finishing Flatpak built in support.

LFS complete with KDE Plasma, Sysvinit, BTRFS.

It was hard work, but it was worth it. The result was exactly as I expected, only lighter and more agile than I anticipated.

u/Due-Celery4326 — 3 days ago

Almost completed with my build

Been busy working on it, on my off days it’s coming along pretty well I think. 14 Day progress.

Rigid C++: Calling for your opinion

Hey folks,

I wrote a C++ manifesto based on my experience as a decade long C++ systems and graphics programmer. Rigid C++ is especially targeted at engine devs.

Would love to hear your feedback and critiques!

Thinking About Building My Own Linux Distribution with LFS – Looking for Advice

Hi everyone,

I'm an intermediate Linux user interested in creating my own distro with LFS. Can I start the process without knowing Bash scripting yet, and learn it along the way?

Any tips or recommendations are welcome. Thanks!

What is the difference between LFS and absolutely nothing?

What I mean by "nothing" is absolutely nothing installed. It would boot into the BIOS and display an error, or simply just have a manual type in terminal, but I'm not sure what would happen if a PC booted into NO OS. What is the difference between LFS and an empty terminal? What simple tools does LFS provide, other than a book to help you get started?

My 4th Gnome Linux From Scratch install

How many times you have installed Linux From Scratch ?

My 4th install was completely automated with scripts for each package.

Help out a fellow lfs user

So i was around halfway through blfs, dealing with the audio drivers and i ran into many issues, like my physical sound card not being detected despite having looked through all the audio settings have enabling ones i need so after 2 recompilations, i decided to grab my config.gz from arch and use it which somehow miraculously still didn't work but I made the stupid mistake of not backing up my previous kernel image and completely overwriting it. Now it's stuck at a black screen and can't even get past grub so would some please kindly share their config.gz. TLDR i fucked up my kernel and i'm asking for someone else's config.gz

I finally released the source code for Depot, my package manager for Vertex Linux

After working on it privately for a while, I’ve finally released the source code for Depot, the package manager I’m building for my Linux-from-scratch distribution, Vertex Linux.

Depot is written in Rust and is designed around building and managing packages without depending on an existing distribution’s package ecosystem. It uses TOML based package recipes, so I dont have to write full scripts.

The project is still under active development, so there are definitely incomplete parts. I’m releasing it now because I think having other people inspect the implementation, test it, and point out questionable design decisions will be more useful than continuing to develop it entirely in private.

Repository: https://github.com/SFGOS/Depot

I’d especially appreciate feedback from anyone who has written a package manager, or just an LFS system in general. (hell even gentoo)
