How would I make a Linux distribution?

[andrewthompson555]

Hello.

I really want to make my own Linux distribution. I only want to build the Linux kernel and make it run a shell. I might want to even add packages like Gnome or KDE.

I am not just looking for something to do (I'm not someone who play games and just wants to make something in 5 minutes). I am really serious about creating a distribution. I have looked into LFS (Linux From Scratch) but that seems a little too heavy.

I don't want SuseStudio or Ubuntu kits. I want to build things from source. There is no point of using online tools when you can just tap on a button. You might as well just install Ubuntu, customise it and say you made it.

I am experienced with some C and Java (If you think I'm saying I want to make it all in Java, I am not because it requires a JVM and it is impossible). I would prefer it if I could find something that could help me learn how to actually use Assembly and C to make an OS.

Please help.

Thank you
Andrew.

Hi,

LFS is your best bet. Your other alternative would be to code all the user-space from scratch, but if you think that LFS is too heavy, then you certainly can't handle writing all the user-space.

LFS is about as light as it gets. I think, perhaps, that you underestimate what is involved.

Then learn how the Linux kernel boots. Less than a week ago, you posted the exact same question about making an OpenBSD distribution.
In general, the boot loader loads the Linux kernel, an initrd and passes parameters to the kernel. You should specify in these parameters to use the initrd as the root file system, and Linux will execute /sbin/init or similar. You put your initialization code there.
Linux From Scratch, as already mentioned, is your best resource for this.

You need more than just the kernel and the bash executable to make bash run. That's what LFS teaches you.

You need to fully understand how the kernel works, what supporting software it needs, and how it interacts with the kernel. This is what you find "too heavy" in LFS.

Maybe the Linux kernel and a busybox initrd would be better then?

Just pass "init=/bin/bash" to linux kernel. Done. (It won't work though, because init scripts initialize a LOT of userspace stuff)

It will work, but probably without job control(Linux uses it as a fallback if it can't find an init script).
