One of the most important early decisions when building a Linux distribution is the scope of supported hardware. The distribution’s default compiler flags are significant for hardware-platform compatibility. Programs that use newer CPU instructions might not run on older CPUs. In this article, I discuss a new approach to building the x86-64 variant of Red Hat Enterprise Linux (RHEL) 9 and share Red Hat’s recommendation for that build.
