What's a transaction? What > are "all of these"? What does it mean for a transaction to be loaded? a transaction is the set of items that will be changed on the system: if you tell yum to 'update' it will find the set of packages that need to be updated and list them in the transaction set as to be updated. Then when you're in the yum shell and you type 'transaction run', 'ts run' or just 'run' it executes the set of commands in that transaction set. -sv
