I'm a bit out of the loop on RHEL, but a large reason for the specific kernel versions is to maintain API/ABI compatibility.
One of the reason, at the place were we ran about 100's of RHEL/CentOS instances, he stayed with RHEL-ish installs was to maintain API compatibility through out the lifecycle of the OS version.
I've now moved on to places were that isn't that specific need. But I still have a few smaller projects that I use RHEL/CentOS/Rocky/etc. because of the stability that those built into the releases.
- boomboomsubban 4y agoI don't see why that would explain why they picked 5.14 rather than the LTS kernel of 5.15, unless LTS support regularly breaks API/ABI compatibility.
- mkovach 4y agoThat part I couldn't tell you, but I haven't look into it much lately.
- awill 4y agoIt is because they don't need the community's help. They have a huge kernel team, and do all their own backporting. The RHEL 5.14 kernel is quite different from the vanilla 5.14 kernel, making the community's help not that useful.
