Currently many arches use in CHOST "gentoo" as vendor field for musl only, e.g., on amd64 "x86_64-gentoo-linux-musl". This is * unnecessary * somewhat silly * and may lead to trouble once other toolchains come into play (llvm, rust, ...) As discussed already with Sam, let's get rid of this (and use the same vendor as for glibc, i.e., -pc- or -unknown-) in profiles 23.0. Bug filed for tracking

Hi, will it still be possible to override the CHOST values in make.conf? I'm still using an older musl install with -gentoo- prefix, can I still upgrade it to the 23.0 profiles once they get stabilized? thanks
Setting CHOST in make.conf should still work. If you want to switch to the new CHOST value, see the wiki page below. https://wiki.gentoo.org/wiki/Changing_the_CHOST_variable

So, yes, sure you will be able to upgrade. See the work-in-progess page, https://wiki.gentoo.org/wiki/Project:Toolchain/23.0_update_instructions

Rust seems to prefer *-unknown-linux-musl[0], so does Void on x86_64[1]. Void on i686[2], as well as Sabotage[3], use i686-linux-musl. I'm not aware of any musl-based distro that uses *-pc-linux-musl, so we seem to be trading one incompatibility for another. In my experience of running Gentoo with musl for almost a decade now, *-gentoo-* has been nothing but problems. I have since dropped the vendor field altogether from all my systems and migrated them to *-linux-musl (arm, aarch64, i686, x86_64). All relevant tools seem to correctly equate the missing vendor field to 'unknown' which is the generally supported tuple. I think we should either: (a) get rid of the (IMHO deprecated and definitely useless in the context of Gentoo) vendor field, or (b) set the vendor field to unknown for all arches.

This is fixed in the 23.0 profiles (available and stable now). Closing.
