understood. i just didn't want you to worry about installing it on all your cluster nodes. > I am NOT running xinetd. I took out the xinetd code. We did this with > version 0.1 and it worked ok. Is xinetd required now? yes. or any inetd-like service daemon. authd is a standalone daemon but we built gexecd to be an xinetd service. a previous execution environment we developed used a mega standalone daemon which fork/exec'd jobs and we found it to be too unstable. xinetd processes are nicely separated in different resource spaces.. so that another user cannot crash gexecd and bring everyone else down with him. > There is a gexecd in /usr/sbin.
