[SAC] xblade14: yum mirror list fixed

[Markus Neteler]

HI SAC,

I have fixed the broken yum repos (server no longer existed) on xblade14.

For convenience I have scripted it (so interested admins may
replicate it as needed on other FC4 blades):

cd /etc/yum.repos.d/
mkdir oldfiles
mv * oldfiles/
cd oldfiles

# this recreates updated files in the parent dir:
/etc/yum.repos.d/oldfiles/fix_repo_urls.sh

# done.

now yum works again on that blade.

cheers
Markus
