With the new 6.15 development kernel, the Canonical Kernel Team has also rolled out the long-planned deprecation of the linux-modules-extra package (see LP#2042831), shipping all the kernel modules via the linux-modules package, which is installed by default on all systems. This change aims to simplify our build infrastructure and, more importantly, remove the need for some of our users to install an extra package to obtain full kernel support on their systems. The linux-modules-extra package was originally introduced when storage size was a significant concern, particularly on small devices. However, with zstd being used by the kernel as the default compression method, the total install size of linux-modules plus linux-modules-extra is smaller than the previous size of linux-modules alone. We anticipate a seamless transition, but please contact us if you have any questions or encounter issues.
Oh this is nice!
