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
