      Why use Gzip to compress kernel modules? Seems like an odd choice.

        Indeed. Zstd is much better these days. The next kernel will have new perf optimizations.

          No support in BusyBox for zstd?

            How is it related? The .ko files are compressed by the kernel make scripts.

              Maybe compatibility? Zstd in kernel is a fairly new feature...

                Are they going to compete with OpenWRT? It seems interesting.

                I would like Zstd being used, among other stuff.

                What about musl vs picolibc?

                  But it is kmod that loads them and alpine uses busybox-modprobe by default.
                  Using zstd over gzip saves something like 1meg while needing 30meg to include zmod. Let loss overall

                    The kmod/insmod/modprobe tools decompress the module. The kernel never does.

                    Doesnt seem to be much progress, but a patch for bb is available:
