So you removed them manually? I'd like to understand what happened, to fix Buildroot if needed. > do I need the other libnss_*.so files? By default, we only copy libnss_dns (to do DNS resolution) and libnss_files (to do /etc/hosts based resolution), and we don't copy the other libnss_* libraries, which are used for more advanced name resolution that are generally not used on most embedded systems. See 'man nsswitch.conf' for more details. Best regards, Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
