Just wait till you see how hard it is to use the arch repos on puppy linux!

The Redhat folks develop software for Redhat. The software will run fine on any other distro with up to date kernels and systemd versions, but there's no guarantee that it does because it's not Redhat's business to work on the OS of their competitors.

If Debian and Ubuntu are too slow to update, that's completely out of Redhat's control. They chose to pin an older version of a piece of software developed in a much more rolling release schedule, it's up to them to fix the incompatibilities their choice introduced. The whole point of an LTS is that you use one older version for several years.

I expect Podman 4.4 to be available in Ubuntu 23.10, as 23.04 is a bit close (current repos list 3.4.4, the version used in 22.04 and 22.10). If Ubuntu can't move fast enough to include it in 23.10, then that's Ubuntus's fault more than anything. You should also consider that Canonical sells their own competing container ecosystem (Charmed/microk8s) to businesses so not supporting their competitors' software may be intentional.

If you want Podman 4.4 but don't want to use Redhat distributions, Arch and derivatives already have it ready to go. You'll also get much more recent versions of the Linux kernel and systemd as a nice bonus.
