How about `make isoimage` for creating a bootable kernel image?

Hey @Maple-Circuit I usually watch your videos on TV so I can't comment on your videos, you seem to know a lot about Linux and that's amazing, I'm a subscriber and I'm here to ask is there any way for me to reach you other than youtube comments?

Didn't we forget to create the /proc and /sys directories or did I miss something ?

I'd love a video about how the lost+found folder and recovery worked. On one scary close call I discovered in there the video of my first child seeing their baby sister for the first time... Glad that recovery found that...

When Gentoo is too easy for you:

Thanks Chad

partprobe makes the kernel automatically detect that your disk image has partitions and it will create /dev/loop15p1 without manually putting the 1MB offset. Other comments have mentioned losetup with the -P option, that just calls partprobe for you as part of the losetup execution

I think this is a cool idea. I'd like to see you build a text mode productivity suite which might include nano, tmux, tty-clock, calcurse, wordgrinder, sc, and tpp.

extra part

I would like to see a homebrew shell. Maybe something LISPy, so it is easy to code.

more like lingua franca nova, amirite fellas? (she said, fully aware of the fact that it is unlikely anyone else will see this comment that has watched conlang critic)

Incredible video, I always had the curiosity to do something like this but couldn't find any resources. Do you have any books or other resources that one could read to expand their knowledge on this stuff?

This is so good!!! 🤩 🐧💪

Down vote for busybox 😐 Edit: to be clear I liked the video - but busybox is a way of sidestepping some really important things. Using busybox is more of an IoT pathway for Linux - which can be very frustrating down the line. I know - I’ve done it before - it’s worth taking the time to implement various packages for a release. Not only does it establish good software practices but it keeps things open-ended whereas busybox just makes a lot of the decisions for you. And they’re not always the best ones.

You can use losetup -p to create a partitioned loop block device.

When you created initramfs.cpio, you could have created it as ../initramfs.cpio to avoid including a half completed initramfs.cpio within the archive. That's why you got the "cpio: FIle ./initramfs.cpio grew, 2526720 new bytes not copied" message.

in the next episode we will be making our own silicon dies

nice use of busybox. 10/10

GIT is pronounced the word "git". JIT is something else (Just-In-Time... recompiler, used for emulation)

pure dead brilliant video thank you good sir LFN!

Very interesting! Was thinking about writing something with Go (which very easily compiles to a static executable) that boots using only a kernel. This would be a great start ;) Hope this series keeps going. I think the next step would be getting networking and file-systems working?

in next vid you should probably add some driver for disk and FS

LFN. This is really very interesting. The applications for this are intriguing. For example, a LFN for running docker.

Any chance of a LFN with BTRFS and OSTREE?

omg this is so inspiring. Now how do we make a functional userspace? since that is all running on root

typing "clear" instead of just hitting ctl-L is certainly a choice...

LFN add fuse and squashfs readability to automount, expanding the linux system overlay...

For EFI systems you could just use EFI Stub and basically drops the need of a bootloader

LFN seeing snap making so many loopback devices makes me cringe, why use snap man 😭

LFN

had to do it from a slackware source cd back in the day had no internet connection

2:17 LFN Why would it be assumed that I'd have a 64 bit system to compile my distributed operating system?

ah yes, the lovely loop device spam of snapd, you love to see it. such a great packaging format.

I don't think you need an offset and two loops when formatting the boot partition. If you include the -P option with losetup, a partscan will be done and you will find both the device and the created partition with lsblk (the partition in this case would be under loop15 called /dev/loop15p1, as in partition 1). Does not really matter, but less confusing than using two loops. You can then interact with the loop as if it was a normal device, create more partitions and filesystems or whatnot. At least that is what I do with my rpi backup script, creating minimal img file and then sync with rsync. :)

Please please please keep this (hopefully) series going!!!

Great stuff, LFN!

I might try this. I'll probably learn a few things. It isn't too crazy...

LFG! erm...

need more LFS and LFN content, its fantastic

I think next logical step would be making an installer out of that image which will replicate the system (except the installer) and will add some additional program on the target system

By you pronouncing git as jit it reinforces to me that gif is still in fact pronounced gif and not jif.

I did many LFS in the past, but nowadays I use buildroot for that, at least you don't need to do everything manually, and plus you have a bunch of extra arch available

Very nice and concise explanation! I just wonder... isn't it a bit of a stretch to call it a "distro"? It's a bootable linux system, that's all.

Obligatory "Can it run DOOM?" Chocolate Doom just depends on SDL, and there are even ports that run in the framebuffer without a display server, so should be doable

this video is so great. ive been wanting to experiment with busybox on the bare kernel but always got an error regarding TC. i never had enough info on how busybox works, until now! i disabled it and it compiled flawlessly. thx!! :)))

LFN project real??? This is gonna be GOOOODD!!!

From nothing!? I hope that means a full source bootstrap. No precompiled compilers allowed! /j obviously
