Further to what Alastair says later in the thread:
what if a yum plugin stored the information about what a script file 
actions looked like before/after the rpm install modified a file ?

yum install foo
[foo renamed /etc/foo.cfg to /etc/foo.cfg.rpmold: versioned at ...]
[foo created /etc/foo.cfg: versioned at /var/cache/rollback/...]

I guess that is a bit simplified; it's not just config files that can 
get modified in scriptlets. Perhaps you could version the /etc/ folder 
and commit any change after each yum transaction ?
