I think this part of the documentation should point to existing
embedded Linux build systems, which already do this job, with several
* Well-tested and proven packages for the most common open-source
components needed in embedded Linux systems
* Cross-compilation issues that arise with the most common packages
are already fixed by those build systems. For example, try to
cross-compile Python. It is basically impossible without heavily
patching its build system. Which is already done by OpenEmbedded,
Buildroot, OpenBricks and all those projects.
* The build process is reproducible. I have encountered way too many
embedded Linux systems built manually, for which nobody knows the
build procedure and nobody is capable of replacing a given component
by a newer version of that component to fix a bug.
To me, suggesting people to manually create their root filesystem is a
