Hi,

I've also faced this problem, and you're right:  relying on timestamps 
and/or sort order of the RPM filenames doesn't work.

The best tool I've found is "repomanage.py" from the yum-utils package 
available at:
http://yum.baseurl.org/download/yum-utils/

Even though yum-utils claims it needs a newer version of yum than I 
usually have, I've run the repomanage.py script that's included without 
any problems.

My typical use has been:

repomanage.py -o RPMS | xargs rm -f

where 'RPMS' is a directory with a whole mess of RPMs.  The 
repomanage.py script with '-o' as an argument spits out only obsoleted 
RPMs, so the above command removes all but the most recent version.

I see that there's a '--keep' option that *might* do what you're looking 
for (keeping the last 3 or 4 versions), but I have not used this option 
before.

-Greg
