Looks like it's about a year of returning to Debian via a Sid install . . . and overall it's been fine, system boots fast and runs well. Recently I found that my Lubuntu kinetic install was still running a 5.13 kernel and there was some other issue with the system and the forum/list-serve suggested that "it should be on 5.19xxx" and also "running such an ancient kernel could be a security sieve" . . . .
I responded, "well, across my numerous linux installs are a range of kernels, even Sid is still running 5.10 kernel . . . ." And I got the response, "That's not right, Sid should be on 5.19 as well . . . ." ????
So, today is "Sid" day on my desktop and I ran "uname -r" and sure enough "5.10" was the running kernel . . . . I launched synaptic and in "kernels and modules" it showed 5.10 as the only kernel installed, and then there were a few options for 5.19.0 . . . "image" "headers" and so forth. I selected a few of them and it found some other dependencies to install and I applied them and rebooted over into the master Grub controller, TW and updated the bootloader.
On cold boot, back into Sid and uname -r does show "5.19.0" . . . as the running kernel. I ran apt upgrade and a few packages to "autoremove" were there, did that, and then ran "autoclean" and that showed that it removed some "5.19" packages, as well as rsync, that synaptic had just installed??

The question for this post is, why was Sid running an old 5.10 kernel, and why wasn't apt showing newer kernels to upgrade into . . . "automatically" versus having to do it "manually"???? My understanding was that Sid is "the cutting edge's cutting edge" and I assumed that meant, bleeding edge kernels??? Now that 5.19.0 is installed, will apt offer newer options or something has to be checked somewhere to get that to happen?? Looks like my TW install is running 5.19.10 . . . . Historically in my debian/ubuntu installs apt kept the kernels fresh . . . not the "newest" . . . but the newest stable kernel . . . something seems to have changed, now kernel upgrading is a separate process???
