Hi Mark!
This guideline, and the code comment in 'gnu/packages/linux.scm', don't make sense to me.All of the kernel packages offered by Guix right now are current LTS kernels. Do you mean "Always points to the newest released LTS version?"
Yours makes it more clear. So, linux-libre => Always points to the latest released version. linux-libre-lts => Always points to the newest released LTS version. Regards, RG.
