The Wiki page https://wiki.gentoo.org/wiki/Project:Toolchain/libcrypt_implementation recommends to add =sys-libs/glibc-2.33-r5 to /etc/portage/package.accept_keywords. This doesn't work any longer, because glibc-2.33-r5 was removed from the tree. Reproducible: Always
Done, thanks: https://wiki.gentoo.org/index.php?title=Project:Toolchain/libcrypt_implementation&diff=1018605&oldid=1010973.
