This is a bug in Glibc: when a service can't be found, NSS should continue to the next service unless "UNAVAIL=return" is set. ("NOTFOUND=return" refers to the service returning a NOTFOUND error, not the service itself not being found.) The reason is that the "status" variable (while initialised to UNAVAIL) is outside of the loop that iterates over the services, the "files" service sets status to NOTFOUND. So when the call to find "mdns4_minimal" fails, "status" will still be NOTFOUND, and it will return instead of continuing to "dns". Thus, the line hosts: mdns4_minimal [NOTFOUND=return] dns mdns4 does work because "status" will contain UNAVAIL after the failure to find mdns4_minimal. */ ./nss-skip-unavail.patch /* Have rpcgen(1) look for cpp(1) in $PATH. */ ./rpcgen-path.patch /* Allow NixOS and Nix to handle the locale-archive. */ ./nix-locale-archive.patch /* Don't use /etc/ld.so.cache, for non-NixOS systems.
