CERN Transitioning Computers To Debian After Being A Longtime RHEL Institution

> CERN engineers had considered moving to CentOS Stream as a more natural pathway but ultimately they say "the straw that broke the camel's back" to abandon Red Hat Enterprise Linux for their industrial accelerator-control computers was the "-march=x86-64-v2" compiler flag default as "forced obsolescence" for old hardware. Incompatibility with x86-64-v2 means that CERN is running some older machines, over 15 years old: https://en.wikipedia.org/wiki/X86-64#Microarchitecture_level...

They could have used gentoo with their own binary package server. Maximum flexibility, including all compiler flags.

Good, I wonder how much money they’ve wasted over the years paying for RHEL.
