"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. svn path=/nixpkgs/branches/stdenv-updates/; revision=11487

/* 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. */
