scientific linux 产品生命周期
Scientific Linux是一种基于Red Hat Enterprise Linux (RHEL)的自由开源Linux操作系统。它旨在为科学研究提供一个稳定、高性能、易于管理的操作系统。SL由美国费米实验室、欧洲核子研究组织 (CERN) 和其他国际机构共同开发和维护，是一种“重打补丁”的版本，与RHEL完全兼容，并且几乎按照相同的时间表发布，但SL在保持二进制兼容性的同时提供了一些自己的改进和补丁。
然而，2019年3月，SL的维护者宣布将不再继续为SL提供支持和更新。作为替代选择，他们提供了CentOS，这是一个类似于SL的免费的重构版本，与RHEL完全兼容。
