Note, enable nscd on the build machine might be a solution, but that isn't reliable since it depends on whether the network function has been cached or not.

You probably also want to change it to use := instead of ??= so that /etc/passwd is only parsed once. This might require to introduce another variable: UID_IS_NONLOCAL := "${@0 if oe.utils.is_local_uid() else 1}" BB_TASK_NETWORK ??= "${UID_IS_NONLOCAL}"
We may not need this any more since NIS seems that is the only case which doesn't work, and can't be fixed (or not easy to fix) by set network per task.
