The file /etc/init.d/yum-updateonboot throw away yum output by sending to /dev/null.

Please use "-q" parameter instead and allow this to be configurable possibly by adding one more variable to /etc/sysconfig/yum-updateonboot with default value "-q" (to preserve old behavior) to every occurence of youm usage in /etc/init.d/yum-updateonboot.

Personally, I would like to allow users to see yum output when update process running (and I'm asking here to be this option configurable). With no message (even progress bar) on boot screen, my users here tends to reboot computer (thinking about freeze), breaks RPM database then and forces me to fix it for them. Fedora updates flow is considerable huge, so the delay with no message when the system is booted is long when the update process is running.

Thang you a lot for your work!
