The problem is a completely different one: the result of getent passwd
and the contents of /etc/passwd are not equivalent. So in case of a
hardlinked file the result is a completely different (just it) then if
the script creates a new one (the contents all nss databases).
Okay, to be exact: getent passwd may not provide a complete view anyway
(because of query limits or so in case of remote databases, like ldap).

It have to replace the old file in this case anyway and not truncate it.
