[Yum-devel] Please fix terrible interaction of yum-cron with yum-merge-conf

[Neal Becker]

If you run yum-cron, and have yum-merge-conf, then yum will go into an 
infinite loop generating an infinite email.

Previously this was really annoying.  Today if filled my disk to 100%.

I guess what's needed is for yum-merge-conf to detect whether the tty is 
actually a terminal?  Doesn't quite explain the inifinite loop though.
