I set yum to run nightly, but there are problems. 1) I need http_proxy set. I tried adding a script to /etc/profile.d, but AFAICT, cron isn't executing it. Any suggestions? I don't want to modify yum scripts, because I'm afraid my change will be lost - and this isn't really yum specific. 2) There is no indication of any error in /var/log/cron nor /var/log/yum.log. I expect that running with the proxy, yum would time out and die, but nothing is logged in either place.
