My 50 cents. I run x86_64-unknown-linux-musl from rustup. I still have

RUSTFLAGS=3D"-C target-feature=3D-crt-static"

set. Packages like rocket (web framework) and diesel (ORM) work,
I haven't tried compiling firefox, though. It was planned to create
a triplet $arch-unknown-linux-dynmusl which is meant for hosts running
musl. [1] This hasn't happened yet and instead many bugs have been fixed so
$arch-unknown-linux-musl works as host and not only as a target. It was said,
that they never remove the requirement for -crt-static, because it will
break a lot of build-systems out there, that think $arch-unknown-linux-musl
is only a target for creating static binaries.

[1] https://github.com/rust-lang/rust/issues/59302

So my point is $arch-alpine-linux-musl feels correct. BUT could we just
introduce $arch-unknown-linux-dynmusl=3F Because if we patch crt-static away
on a rust-build using $arch-unknown-linux-musl, we might break things that
expect crt-static. If packages only look at the middle part *-unknown-linux-*
it might fix most problems. Either way it was a very bad idea to link
crt-static with the triplet.

Let me know if you think creating $arch-unknown-linux-dynmusl rust-build
is worth a try=3F

Best,
Jean-Louis
