     @postmarketOS I was very surprised recently that Alpine's musl resolves DNS differently than glibc.

     - https://biriukov.dev/docs/resolver-dual-stack-application/5-getaddrinfo-from-musl-libc/
     - https://jvns.ca/blog/2022/02/23/getaddrinfo-is-kind-of-weird/

     In our case it breaks the search domain for Docker containers which would like to discover each other via DNS. This limitation of the search domain might also apply to mobile devices on postmarketOS in networks that set one.

     @yala @postmarketOS Those blog posts being outdated since musl 1.2.4+ released in May 2023 which added TCP fallback for DNS.
     Then yeah it's doomed to have few bits of differences in resolv.conf as that's a libc-specific config file (although often abused as a system configuration file).
