On recent Debian Edu systems, there are many message in systemd's
journal / syslog referring to /etc/netgroup not being found on the
system:

"/etc/netgroup: No such file or directory"

These messages should be silenced, ideally by creating an empty
/etc/netgroup file (so people can populate it later if they want).

Any idea where these come from.  I know netgroups from LDAP
traditionally have been used in Debian Edu for giving names to groups of
hosts for various purposes, and thus suspect the host local equivalent
might have its uses too, but it seem surprising that the lack of a local
/etc/netgroup should cause such noise, and I suspect the source should
be tracked down and silenced.
