musl libc 1.2.4 – now with TCP fallback in DNS resolver

The no-tcp fallback discussion has come up a few times on HN. Maybe that will unbreak some Kube clusters or at least remove the need for some workarounds.

I just upgraded one of my nameservers and the kernel is 6.1.27-2 was 5.15.109-0 previously. Upgrade appears to have gone fine. A few sysctl's deprecated. Nice and boring, the way I like it.

Bare metal upgrades have been going fine as well.

Can somebody elaborate why would you want to use Alpine instead Clear Linux?

Small optimized container image sizes is one of the reasons.

  alpine image is ~5 MB. [1]
  clearlinux image is ~80 MB. [2]

Alpine also runs on ARM platforms, and by using musl instead of glibc it consumes a lot less resources, at the price of some (thankfully rare) incompatibilities here and there. For reference: https://wiki.musl-libc.org/functional-differences-from-glibc...

Link for anyone interested in Clear Linux: https://clearlinux.org/

Had heard of Alpine and used it plenty for containers, yet hadn't heard of Clear Linux before. Nowadays I just use Ubuntu for my container images (due to the same environment as my dev machine which simplifies things for me), but there's also a lot of benefit and elegance in more lightweight alternatives.
