Re: [CentOS] Dell unofficial community repository - what do you think?
This is correct, the latest firmware updates take a little bit to get packaged and tested before they get pushed to the repo. I also haven't figured out how to only update firmware for specific devices. With the inventory_firmware and update_firmware commands, it looks for updates and applies all updates at once. As for creating a local mirror, a simple rsync grabs it (I exclude everything I don't need) rsync --progress --delete -avHz --exclude=rh30 --exclude=rh30_64 --exclude=rh40 --exclude=rh40_64 --exclude='SLES_*' --exclude='SLE_*' --exclude='suse*' --exclude='sles*' linux.dell.com::repo/hardware/OMSA_7.1/ /yumrepo/repos/dell/hardware/OMSA_7.1/ I also don't use the community repo...I haven't found anything I need in there. I'll attach the yum repo file I use for my local repo. A 'yum install srvadmin-all dell_ft_install' will grab what you need for firmware tools and OpenManage, and then a 'yum install $(bootstrap_firmware)' will grab all your hardware specific firmware.

FWIW, I have this problem with 5.6. Are you installing from a local repo? If you are, try rsyncing the repo again. See if it changes the repodata files at all. I have yet to find why my repodata files are changing for the main repo (I didn't build our original repo servers, there are a bunch of random scripts that run that were created by a previous admin), but re-syncing the repos seems to stop that error from popping up during a kickstart.
