Linux gives up on 6-year LTS kernels, says they’re too much work

The LTS (long-term support) period for the Linux kernel is being cut down. In 2017, the kernel jumped from two years of support to six. Now, six years later, it turns out that's a lot of work. ZDNet reports that at the Open Source Summit Europe this week (videos will be out in a few weeks), Linux Weekly News executive editor Jonathan Corbet announced the Linux kernel will return to two years of LTS support.

The plan to cut back down to two years isn't instant. The Linux community is still honoring the current end-of-life timelines, so 6.1, 5.15, 5.10, 5.4, 4.19, and 4.14 are still six years, but new kernels will only get two years. Even this six-year window was supposed to be an optional thing when it started, with the release page FAQ saying, "Each new longterm kernel usually starts with only a 2-year projected EOL that can be extended further if there is enough interest from the industry at large to help support it for a longer period of time." The reality was that everything received a six-year life span, and now that will no longer be the case.

Corbet cited a mix of lack of use and a lack of support for why Linux is cutting back on LTS kernels. Corbet says, "There's really no point to maintaining [old kernels] for that long because people are not using them." The other big problem is the burnout from maintainers, which are often unpaid and could use a lot more support from the billion-dollar companies that benefit from using Linux.
