欧洲核子研究组织(CERN)和美国费米实验室十多年前从Scientific Linux转向CentOS的决策如今面临质疑。1当Red Hat在2020年12月停止传统CentOS Linux并转向CentOS Stream后，这两家机构被迫重新评估其Linux战略，最终导致CERN决定将加速器复杂系统的超过2200台工业计算机和嵌入式系统迁移至Debian 13，目标完成时间为2026年底。1
Scientific Linux由费米实验室于2003年推出，随后CERN加入，为高能物理社区提供了近二十年的稳定计算平台。1在CentOS战略转变后，这一选择的代价逐渐显现。根据CERN 2023年的风险分析，继续留在Red Hat生态系统的成本约为540万瑞士法郎，并且可能需要重新设计11块电路板、重新组织机架和重新配线。1CERN最终选择Debian，看中其对老旧架构的持续支持以及作为社区主导发行版与Red Hat竞争的能力。1为强化这一选择，CERN正赞助Freexian以加强Debian的长期支持生态系统。1Scientific Linux后期仅由少数主要开发者维护，费米实验室提供了主要赞助、构建基础设施、带宽和网站支持。1
CERN is planning to migrate more than 2,200 industrial computers and embedded systems running its accelerator complex to Debian 13 by the end of 2026, marking a significant shift away from the Red Hat ecosystem 1. This transition reflects a strategic reassessment triggered by Red Hat's decision in December 2020 to discontinue traditional CentOS Linux in favor of CentOS Stream, forcing CERN and Fermilab to reconsider their long-term Linux strategy 1.
Scientific Linux, originally developed by Fermilab in 2003 with CERN subsequently joining as a partner, had provided the high-energy physics community with a stable computing platform for nearly two decades 1. The decision to abandon Scientific Linux in favor of CentOS years earlier now appears problematic. A 2023 risk analysis conducted by CERN estimated that remaining within the Red Hat ecosystem would cost approximately 5.4 million Swiss francs and potentially require redesigning 11 circuit boards, reorganizing racks, and reconfiguring cabling 1.
CERN selected Debian due to its continued support for legacy architectures and its position as a community-driven distribution capable of competing with Red Hat 1. The organization is further supporting this transition by sponsoring Freexian to strengthen Debian's long-term support ecosystem 1.
