First of all, make sure to not confuse Buildroot and OpenWRT. They are
completely different projects, and internally they work completely
differently.

The OpenWRT documentation improperly calls the project "OpenWRT
Buildroot" because OpenWRT was 10+ years ago a fork of Buildroot. But
nowadays, the projects have nothing in common.

If you're really talking about Buildroot (http://buildroot.org), then
please read the documentation at
https://buildroot.org/downloads/manual/manual.html. It gives all the
details about customizing the rootfs, adding more packages, configuring
the kernel, and more.

Best regards,
