Of course YMMV. oh - I know yum-2.0 works on 8 with rpm 4.1.1 - the question was whether or not the byte-compiled modules built on 9 were compatible with the python on 8.0. > > you can't use yum-2.0 on 7.1, 7.2, and 7.3 - and the python for them is > > significantly different. > > :-( So let me be more clear. if you build rpm 4.1.1 on 7.3 and install it then yes, you should be able to run yum-2.0 on 7.3. 7.1 and 7.2 need better python2's and libxml2 iirc. I'd also like to note that you do NOT want to go through that pain. I need to backport some stuff to 1.0.x sometime soon anyway - it's not a dead branch - but I wouldn't expect all the newest features to reach it immediately, either. -sv
