Re: Discussion about file format for the future

Just throwing out an idea here:
If we are going with a database or some sort of keystore for the metadata. 
We can still generate one "keystore" file for each revision. But the 
current mirror metadata could contain the full history.=Making sure we 
could always go back to the previous keystore and recover manually...
