Switch hdds, maintain server?
 

Not really a switch, just an "addon". If I take the drive from my server and add it to my desktop, will the server configuration still work? The only system difference is that the server is running Slackware 11, whereas my desktop is Slackware 12. I would like to maintain everything so I don't have to transfer it over, as the php and mysql modules are all working on it already and I have multiple sites on it.

How well will this work?

Nobody knows?

I'd say you'd probably have a ton of problems. When you mount the drive from SERVERA into SERVERB, you'll probably bring it up under a mount-point, like /mnt/serverb.

The paths for your configs won't be there anymore. The apache service on the serverb drive will be looking in /etc/apache2, which is on the servera drive...the one for serverb will be in /mnt/serverb/etc/apache2. And so on...web page paths will change too, etc., etc.

You're in for a load of work no matter what...having the drive mounted locally will just speed up the file copies, or let you edit things easier.
