@navjotsinghji ack. Thanks for pointing this out and also providing repro steps. We will take a look and update.

Hi @navjotsinghji

The Root-Cause seems to be the lack of /var/run/nscd directory in a container;

~Solution~ Workaround: Before we execute /usr/sbin/nscd; we should create the /var/* dir:

mkdir -p /var/run/nscd /var/db/nscd

The -p option makes this work irrespective of /var/.. dir being present or not. (maybe you may want to run the same script on a vm where these directories are present IMO)
