while using yum update on CentOS 4.4,
i know sometimes rpmnew and rpmsave files are being created.

i found this page with yum output, which includes warnings like :
warning: /etc/sane.d/dll.conf created as /etc/sane.d/dll.conf.rpmnew

when i'm running yum update i never get those warnings, but doing "locate rpmnew" or "locate rpmsave" i do get a few results.

looking at the content of yum.log i cant see any warning inside,
just "updated:" and "installed:".

how do i make my yum tell me (through log\screen output while working) that he created rpmsave\rpmnew that needs to be taken care of ?

thank you all.
