Ljubomir, If you wanna pop by #fedora-devel on freenode tomorrow the mock, yum and createrepo(clark, james, me, tim, nils, panu and others) maintainers and developers tend to all be in there often. the long and short is - yum plugins don't work inside mock overly well and they are tricky to get in there. You could also pop by #yum on freenode, you'll find a lot of similarly good folks around who can help. finally, just to dispel any confusion: yum uses sqlitedbs first if they are available. createrepo generates both the xml and the sqlitedbs, by default repomd.xml is just used for the index to the repo. good luck with your building process. -sv
