Hello,
some weeks ago I looked briefly at the drpms subdirectories for Centos-6.4-x86_64. All updtes took about 4GB whereas the drpms subdir had already 27GB. Listing the drpms directory by size showed e.g. libreoffice updates taking e.g. 35MB whereas the full update rpm is 37MB.
Is it possible to move the drpms directories to special mirrors only. Similar to the debuginfo/source/oldreleases? Maybe also some tuning is possible to generate drpms only if they really give a huge download saving.
Sorry, I don't have detailed numbers anymore, I've just disabled to mirror the drpms subdir for now. (All numbers above are from memory, my local mirror doesn't have drpms anymore.)
Keeping the official CentOS mirror rather small should be a real plus for the large volume of mirror sites and the real good distribution of CentOS.
Thanks a lot for CentOS,
Florian La Roche
