@srtcd424 @owen Not really. In #musl we honor nscd for user/group db because the protocol is workable, we aim not to NIH things, and it gives custom db backend support. But not the nss hostname stuff. It lacks sufficient capability (hosts backend can't do scope ids for link local addresses) and it has broken fallback logic that doesn't treat nonexistence safely, and DNS protocol already provides a more capable way to do custom backend if needed.
