CERN started transitioning to CentOS several years ago. SL was a Fermilab Computing product at this point. I also personally switched from SL to CentOS on my workstation years ago (partially because it took so long for SL7 to come out) .

Fedora is considerably upstream for all three. I expect the efforts are mainly repackaging, so instead of repacking RHEL into SL, they'll aid in the repackaging of RHEL into CentOS.

Fedora Scientific Spin is produced by the Fedora Project's Science and Technology special interest group (SIG). It's based on KDE.

I don't think there's any relationship between this SIG and Scientific Linux.

You mean Fermilab. CERN started moving to CentOS in 2015, Fermilab has finally decided to as well.

I wondered this as well. It sounds like Scientific Linux was more just a convenient and consistent package of applications and interface than any significant changes to linux proper.

However, if the various particle labs who used to use Scientific Linux end up requiring any significant code changes for performance reasons, it seems like this change would mean sharing those changes upstream would face an easier path.
