Description of problem:
The files /etc/profile.d/krb5.* are, for now, marked as %config files, in the 
spec file of devel.

I would like to empty those files. However, at the next upgrade, they will be 
restored (and my version will be *.rpmsave). They should be marked 
as %config(noreplace). Or at least, there should be a way to definitly prevent 
those files to modify the PATH.

Fedora Extras guidelines recommand to use %config(noreplace) at any time, 
instead of %config, but when it is really mandatory.

I think that those files are not the only files that should 
be %config(noreplace). I can see several other %config (without "noreplace") 
in the spec file.
