How is busybox added to the rootfs?

[aw]

Hello,

It seems there are missing some steps in the build process for the TC rootfs.

I found the 3 following files/repos:

- http://repo.tinycorelinux.net/11.x/x86_64/release/src/toolchain/compile_tc11_x86_64
- http://repo.tinycorelinux.net/11.x/x86_64/release/src/busybox/compile_busybox
- https://github.com/tinycorelinux/Core-scripts

But it doesn't explain how Busybox, the kernel, and the compiled binaries get merged into a rootfs. Are there other files added which I'm not aware of? Is there a script somewhere?

Thanks.

I imagine that in the beginning Robert created a rootfs much as lfs do.

Since then the rootfs has been over-written with the new files manually.

There is a sorter script in tinycore git to create the kernel driver extensions.

The kernel does not get merged into the rootfs.

Thanks for the correction regarding the kernel.

Ok so you take an existing rootfs (ex: 10.x), extract with cpio, overwrite the files with 11.x busybox etc, then regenerate the rootfs with cpio?

Affirmative

Hi aw
To unpack:

Code: [Select]

mkdir tempdir
cd tempdir
zcat /path/to/existing/rootfs.gz | sudo cpio -i
To repack:

Code: [Select]

cd tempdir
sudo find . | sudo cpio -o -H newc | gzip > /path/to/new/rootfs.gz
