[CentOS] other repositories question

[dan1]

Hi, Johnny.

Thank you for that 'protect' tag explanation that seems to do exactly what I 
wanted.

Would this 'protect' tag solution also arise the same problem than described 
above ?

Also, does someone know where I could find a list of Dag's repo packages 
that are already present in the CentOS officials ?
If there are only a few ones there, then it might be ok to just add them to 
the repos list as I am doing now already.

Is a downgrade from one higher version package to a current CentOS package 
something doable? I am a bit affraid to do something like that and don't 
know how I would do it (it might influence other packages as well..)

Best regards,
Daniel
