i'm sure there's a simple answer to this -- i already understand that newer kernels than the ones shipped with the official release aren't officially supported but there is the elrepo kernel repository here:
http://elrepo.org/linux/kernel/el7/x86_64/RPMS/
with a mixture of long-term (lt) and mainline (ml) kernels. i assume that the mainline kernels pretty closely track the latest kernel release but that's not the one i'm interested in.
if i was interested in the additional longevity of the LTS kernels, i can see that 4.4 is available. but the most recent LTS kernel was 4.14, was it not? so why is a 4.14 "lt" kernel not available in that repository?
i am obviously unclear on the policy used to determine which kernel versions end up in that repository.
