Looks like I was wrong before about getaddrinfo bypassing /etc/hosts, and it does indeed look at /etc/hosts. $ sudo -u sbuild getent hosts localhost 127.0.0.1 profitbricks-build17-amd64.debian.net profitbricks-build17-amd64 localhost $ sudo -u sbuild getent hosts localhost. # no results However if you change "localhost" in /etc/hosts to "localhost." then the above results would be reversed. What do you think the full behaviour should be? > Also note that technically the glibc doesn't require network access, > just a DNS server able to resolve 'localhost.' > So how do you want to fix this? glibc doesn't currently build-depend on a name server, and I assume you wouldn't want to do that. Can you give me some hints on what to patch, to fix libnss_files? X -- GPG: ed25519/56034877E1F87C35 GPG: rsa4096/1318EFAC5FBBDBCE https://github.com/infinity0/pubkeys.git
