ok, good to know

if it is the presto it would not affect the production server
they have no yum-plugins and using only an internal cache-repo
on the same vmware-ESXi-host which is refreshed from /var/cache/yum
on this machine

[root at buildserver:~]$ cat /buildserver/repo-cache.sh
#!/bin/bash
basearch=`uname -i`
releasever=`rpm -q --qf "%{version}\n" fedora-release`
for g in `ls -1b /var/cache/yum`
do
 if [ -d /var/cache/yum/$g/packages ]
 then
  echo "/var/cache/yum/$g/packages/ > /repo/cache/fc$releasever/"
  sudo cp --verbose /var/cache/yum/$g/packages/*.rpm /repo/cache/fc$releasever/ 2> /dev/null
 fi
done
sudo chown -R builduser:builduser /repo/cache/fc$releasever/
sudo chmod -R 755 /repo/cache/fc$releasever/
