Your basic scenario would be:
1) ssh into server
2) start screen
3) yum update
4) detach screen (yum continues in background)
5) ssh into server again
6) reattach screen
7) check status of yum process, check errors, etc.
8) once yum is finished, reboot
The advantage of doing this with screen is that even if your ssh
connection dies in the middle of typing a command, you can ssh back
into the server, reattach the screen, and be right where you left off.
I can't really speak to the wisdom of yum -y update & as I always
like to know what questions it asks me before I say yes or no.
I hope this was the answer you were looking for,
