March 25, 2025Amazon Linux 2022/2023
Just my musings from having built most these major OS with packer pipelines in the past, I have no affiliation to AWS or special knowledge. AL2022 was the successor to AL2 and had been under dev/testing for years. They just renamed it from AL2022 --> AL2023 a week or so ago. https://github.com/amazonlinux/amazon-linux-2023/pull/275 . I think they originally planned to GA in 2022, hence the name, and that slid out. putting out an OS is hard work. AL (1) was based off RHEL6 (red hat) AL2 was based off RHEL7 AL2023 is fedora based, so moving to more of a rolling release AL in general is derived off another OS and those OS end of life so Amazon shifts to something new which makes sense for supporting packages and such. So the way these fit in is the same as any new OS, RHEL or Ubuntu new releases. Even Windows server releases; 2012-->16-->19 etc. Traditionally, major OS revolve around a major kernel update as well which often made for breaking changes for COTs apps a client may be using. Support for AL and AL2 got extended out past initial EOL for sec updates, just guessing covid and/or getting AL2023 out the door all played in to those decisions. There hasn't in the past been a supported direct upgrade path from major AL releases, so you can't run an upgrade check and do some commands to update and existing server from AL-->AL2. Ive seen folks do that with RHEL. I've personally never been a fan in the past of in-place OS upgrades for linux or windows; so a rebuild by hand or the opportunity to put everything into Ansible or other conf was a fun adventure.

From the Amazon Linux 2023 documentation:
You can change the value of releasever using one of the following methods. These methods are listed in descending system priority. This means that method 1 overrides methods 2 and 3, and method 2 overrides method 3.
- The value in the command line flag, --releasever=latest, if it's used.
- The value that's specified in the override variable file, /etc/dnf/vars/releasever, if it's set.
- The currently installed version of the system-release package.
So releasever can be found with the one-liner:
cat /etc/dnf/vars/releasever || rpm -q system-release
Original answer
Can be found like so:
cat /var/log/dnf.log | grep -i "ddebug releasever:" | rev | cut -f 1 -d " " | rev | tail -n 1
To double check run dnf list system-release. The numbers should be identical.
The packages amazon-linux-repo-s3 or kernel-livepatch-repo-s3 can be used in place of system-release.
