    thank you very much guys for all your time 

    you have set me on the path

    i'll poke around and see if i can learn a little more

It's not a script, it is just build notes - you start at the beginning and work your way to the end 

Hi Juanito, in summary, there is no build script for rootfs.gz even for the current latest TC 16 x86. Is that right?
For example, if one wants to rebuild rootfs.gz, let's say to change

Code: [Select]

--enable-kernel=6.1.2 to

Code: [Select]

--enable-kernel=4.4.302, one would have to

• read the http://tinycorelinux.net/16.x/x86/release/src/toolchain/compile_tc16_x86
• infer the commands to run
• manually run them until reaching the end of the build notes (fixing the errors if some show up or filling the gaps if there are any)
• probably running an additional repacking to generate the rootfs.gz command because the build notes end with "[remove files to match base/extension setup]"

Would that be it?

Also, thank you Juanito everyone for tinycore! It's fascinating!

Not exactly, the "remove files to match base/extension setup" refers to the chroot environment.

To update rootfs.gz, you need to overwrite the existing files with the newly built files (after first stripping them) like this:

Code: [Select]

mkdir /tmp/extract
cd /tmp/extract
zcat /tmp/rootfs.gz | sudo cpio -i -H newc -d
rm /tmp/rootfs.gz

[overwrite/update existing files]

cd /tmp/extract
find | sudo cpio -o -H newc | gzip -2 > ../rootfs.gz
cd /tmp
advdef -z4 rootfs.gz

Would that be it?

Yes
