Sysext images have a compatibility matching mechanism that searches for the matching OS version or custom sysext level setting. On Flatcar there is just the OS version set in /etc/os-release until now which means that sysext images can't easily be used together with autoupdates that change the OS version. Define a sysext level for Flatcar so that users can refer to it instead of the OS version when they have images that don't rely on a particular Flatcar version. Here an example of the now possible metadata: /etc/extensions/NAME/usr/lib64/extension-release.d/extension-release.NAME ID=flatcar SYSEXT_LEVEL=1.0 and a symlink /etc/extensions/NAME/usr/lib → /etc/extensions/NAME/usr/lib64 to work around the problem that using lib/ as path destroys Flatcar's lib → lib64 symlink. In the future the matching logic hopefully gets more flexible because now it is just a string comparison. Also, the architecture is not matched either for now - we should work with upstream to improve this. Closes: https://github.com/flatcar-linux/Flatcar/issues/643 |
