Description of problem:
No centralized way for a system admin or hobbiest (or remote troubleshooter) to
get an accounting of rpmnew or rpmsave files created on rpm updates using any
available rpm update tools. Brute force filesystem searching or indexing has to
be used to find rpmnew/rpmsave files. The situation has become more combersome
now that slocate is turned off by default in fc4. Though relying on slocate for
this in the past has been a crutch. There should be a log of rpmnew/rpmsave
files created at rpm update time as part of the package update process.

The basic issue is one of notification. How should admins of systems be notified
of the creation of rpmnew and rpmsave files?  I personally think a simple log of
these events in a /var/log/ file would serve in all cases. Or any implementation
that allowed for centralized review of rpmnew and rpmsave file creation times. 

A more complete solution would involve librpm being able to pass information
about these rpmsave/rpmnew file creation events to higher level tools so that
each tool could then in turn notify the tool user via the most appropriate ui
for the tool.  Yum for example could choose to log these events in its own log
file and perhaps in the end of transaction stdout summary text. rpm cli tool
might just spit this out to stdout or stderr. If librpm is already doing this
and I am just may be ignorant of this fact, I apologize.

I am most concerned about rpmsave file creation events. Though rare, when they
happen they tend to confuse less experienced admins into thinking something has
broken simply because they don't know about the rpmsave file 'feature'. 
TakefFor example, gdm. Until recently gdm updates generated rpmsave files. A
fair to partly cloudly number of less experienced hobbiests love to theme gdm.
They can be confused when gdm loses its theme information and they don't
recongnize this as a packaging feature. They unfortunately see it as a bug in
gdm. I think that finding a way to notify admins/hobbiests of rpmsave/rpmnew
creation events when they occur will go along way to mitigate confusion,
especially for novices.
