Eelco Dolstra 7d96471775 * Ignore services in nsswitch.conf that cannot be found (like
"mdns4_mininal" on Ubuntu).  This is a fix for NIXPKGS-79.  It
  doesn't *quite* fix the problem in all cases (there might be people
  actually using mDNS; they should just run the "nscd" daemon) but at
  least it should keep curl from failing in Nixpkgs downloads.

/* Fix for NIXPKGS-79: when doing host name lookups, when
nsswitch.conf contains a line like
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
don't return an error when mdns4_minimal can't be found. 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. */
