[olug] Fedora upgrade time again

[Lou Duchez]

Version 22 came out the other week, so it was upgrade time.

Ever since they came out with the "fedora-upgrade" script, it's been 
super easy.  Here's what you do:

yum update
yum install fedora-upgrade
fedora-upgrade
reboot

And that's it.  Five out of five servers rebooted happily to Fedora 22.  
The only headache was that I had to run "chkconfig dhcpd on" and 
"systemctl start dhcpd.service" on those servers that were running DHCP, 
but that's the sort of thing that happens sometimes.
