Is this just the same as #193?

[raylu]

ah, yes it is!

although I'm confused why/how the musl versions support it then

[geofft]

We seem to target a newer baseline OS for the musl builds - for glibc we try to be compatible with OSes from around ~2014 (for most architectures we build on Debian 8/glibc 2.17), but for the dynamic musl builds we are targeting ~2022 (we build on Ubuntu 22.04/musl 1.2.2). I think it's just that nobody has asked for older musl builds, since the target audience is usually users of the alpine:latest Docker image. And the static musl builds don't need to be compatible with any version already installed on the system, so we use the latest available version (1.2.5) for them.

That's correct, e.g., see #541 (comment)
