The difference is that the comps file isn't allowed to do anything more than list an exact package name. Listing packages in %packages is allowed to be globs, specify version, specify, arch, etc. Although I'm not quite sure why we're not using the matchPackageNames() bits in yum's install() method... it should provide the same sort of results but also be able to do some of the querying using sql queries against the sqlite db (and thus probably be faster) Jeremy
