On a 5.1 machine ready for 5.2:
# yum update >/tmp/update.log n # yum upgrade >/tmp/upgrade.log n # diff /tmp/update.log /tmp/upgrade.log 2c2
< Setting up Update Process
Setting up Upgrade Process
Looks to me that update==upgrade.
Why does the announcement of 5.2 say it is important to use "yum upgrade"?
Because ... if you have every modified your yum.conf file then it is NOT replaced by updates. Therefore MANY CentOS users may not have obsoletes=1 set in their yum.conf file
Since there is a possible difference, using "yum upgrade" instead of "yum update" works for everyone ... yum update may or may not work.
If you were going to have one set of instructions, which should it be ... one that works for everyone or one that might or might not work :D
