Hi,
We update all the boxes over ssh. Works fine. Those who are afraid of
disconnections may always run it within tmux/screen session. As to
managing the whole infra, the best tool for that is Spacewalk, but it
might be too big for you. So, you can have nagios to check yum status on
all the boxes. There is also a tool called apt-dater, see
http://www.ibh.de/apt-dater/ Regardless the "APT" in the name it handles
yum well.
