[OpenAFS] Please explain RPM packaging of config files like ThisCell and CellServeDB

[Simon Wilkinson]

Here's what currently happens with the RPMs from openafs.org (note  
that there are other OpenAFS builds available, which will have  
different behaviour).

We don't distribute a 'CellServDB' file as such. Instead, the RPM has  
a script that runs immediately following installation which combines  
the contents of CellServDB.dist (which comes from the RPM) and  
CellServDB.local (in which you can make local additions) to produce  
CellServDB. CellServDB is the only file that is read by OpenAFS itself.

'ThisCell'  and 'cacheinfo' are marked as configuration files in the  
RPM spec. This means that if we don't change them between releases,  
then any changes you make will remain in place. However, if something  
in those files changes between releases, your changes will be moved  
to a '.rpmorig' file, and the ones from the RPM installed. This is  
probably suboptimal - I'll look at fixing this.

If you have a CellServDB.rpmorig, it suggests that you're not using  
the current OpenAFS RPMs. How recently was that file created?

Cheers,

Simon.
