I fail to understand how a snapshot would differentiate between yum
related changes and other changes that occur by an otherwise normally
operating daemon (logs for example).

Certainly you don't want to loose your logs when you want to revert a
yum update ?

What if you loose is something more important, like shared secrets (a
kerberos keytab) that have changed during the transaction ?

Simo.
