Prefer glibc then fallback to musl if glibc build is not published

[hongquan]

I use mise on an Ubuntu Linux machine. When mise installs ruff, it automatically picks the musl build:

❯ mise upgrade
ruff@0.16.3                  extract ruff-x86_64-unknown-linux-musl.tar.gz                                                                     ✔

even though that my OS is glibc-based and Ruff glibc builds is available.
If I use this settings:

[settings]
libc = "glibc"

mise will only looks for glibc and denies to install softwares that are built with musl only.

How to tell mise to prefer glibc but fallback to musl if glibc build is not available?

Thanks for the report. The immediate Ruff behavior comes from the Aqua registry entry, which hard-codes unknown-linux-musl even though Ruff publishes both GNU and musl artifacts.

Please submit a PR upstream to aquaproj/aqua-registry that changes the Ruff package metadata to use the GNU target by default and a libc-specific musl override. That will make the metadata accurate for mise and other Aqua consumers.

There is also a generic mise-side gap: an automatically detected glibc host had no “prefer glibc, then fall back to musl” behavior. I opened #12093 to add that behavior while keeping explicit libc = "glibc" and libc = "musl" settings strict.

Submitted to Aqua Registry but they explicitly prefer musl.

yeah I think that's a mistake
