Getting Linux Distros to New Architectures
summary
Automated bootstrap scripts produce cross toolchains, a minimal chroot and an ordered package build list that resolves circular deps and rebuilds components like libc or Python when needed. Uses GCC/Clang cross targets, RPM macros to select compilers and detect native execution, QEMU for verification and an OS image Builder that handles per-device kernels and partition layouts. Successfully bootstrapped an OpenMandriva RISC‑V port (built on an aarch64 Amp Ultra) with RPM macros for cross-compiling and automated bootstrap scripts to reproduce images.
