You do not HAVE to run createrepo unless you want to do so, and in fact
I recommend that you don't.
We do serveral things with createrepo, including providing deltarpms
(the yum-presto plugin) for updates where a usually much smaller DELTA
is downloaded for updates rather than the entire package.
The options that we use for createrepo are:
createrepo -g <path_to_comps.xml> -d --unique-md-filenames --deltas
--num-deltas=5 --update --oldpackagedirs=<path_to_old_packages> .
Note: The -g allows for groups and is optional.
Note: There are usually more than one --oldpackagedirs=<path>,
depending on where the old packages reside.
