Author: rafan Date: Mon Jan 5 13:06:03 2009 New Revision: 186772 URL: http://svn.freebsd.org/changeset/base/186772 Log: MFC r184459 - Whenever a password/shell is changed via rpc.yppasswdd, the daemon leaves one zombie process because it does not do the cleanup. For a long running NIS/YP server, it will have lots of zombie processes on it. Fix that by ignoring the SIGCHLD signal since we don't really care about the exit status in this case.
