[Phpmyadmin-devel] Config import proposal

Hi Michal and all,

indeed I would love to get rid of the $cfg['FileRevision'] mechanism.

I agree with your first idea. We could even do this: at run time, if 
config.inc.php is not there, try to create it from config.default.php 
and inform the user if it works or if it fails (could fail because of 
safe mode restrictions or just permission problems).

This way, we keep the current behavior that a default PMA installation 
works immediately without doing anything, permitting to connect to a 
default MySQL installation with root and no password (yeah!).

Note that at some places in the code we set some parts of $cfg 
dynamically based on the MySQL version, but this should not be a problem.

Let's not forget also config.inc.developer.php :)
