Ubuntu LTS kernels will (still) get one decade of fixes

Not sure if this is such a big deal. Sounds like a big deal if you're stuck with the CentOS mindset and looking for an alternative.

I have been using Ubuntu and Pop!OS (both 22.04LTS) side by side for a couple of years. One difference is that Ubuntu has been busy backporting and patching fixes into the 5.15 kernel, the System76 fork has steadily upgraded the kernel — I think we're at 6.4.

Haven't run into a single problem with Pop! that I attribute to this, and I think this is the more sane approach. Of course there is pressure to not upgrade, don't fix things that ain't broken. But stuff will inevitably break anyway: leave a service unpatched and you get hacked OR change something a 1000 times and at some point you'll run into an unforeseen interoperability issue.

So if (for whatever reason) I were forced to stay pinned to over a decade to a specific distro version, I'm not so sure I would trust these type of long-distance backports over keeping current that parts that can more or less "safely" be kept current.
