I'm building an OS, and blogging about it. Here is Day 1

I would recommend NOT using "Linux from Scratch". LfS is great if you want to understand how Linux is configured and built. But as a general OS reference work it is lacking.

Instead look at XV6 (https://pdos.csail.mit.edu/6.828/2012/xv6.html), IMHO opinion it is a cleaner, simpler work and has some excellent educational materials as well.

Is this a rite of passage? Seems there are hundreds of OS's out there, most of which remain the creator's pet.

BTW: your linked web address doesn't seem to work.

Agreed. Linux from scratch pretty much has zero to do with writing an an os from scratch.

I'll check it out! I'm not sure about a rite of passage but it is a challenge and builds new skills and knowledge. I think I am going to learn alot through this process and have a really cool portfolio piece at the end of it!

xv6 is still my favourite:

- The codebase is very small. Study the PDF references a few days, and eventually you'll start to understand how things work.

- No convoluted build system. Just "make xv6.img". Done.

- No need to build a custom compiler from source. On Linux systems: GCC supplied by your favourite package manager is sufficient. On Mac: install i386-elf-toolchain via Homebrew.

- Plenty of folks customizing it, like adding their own syscalls or a custom scheduler or a file system integrity check (Github is your friend).
