Naming convention for computers
Background: Because of hardware failure, I was tasked with setting up a replacement server this evening. Because it was a replacement, I named it the exact same name as the original server. Because the shell prompt were identical on both machines, I ended up accidentally overwriting some configuration files in the original server with the default config files in the new server. DOH!
Luckily, we had backups and this was a test server. Otherwise I'd of been making a post in a previous serverfault question.
Question: This got me wondering what naming conventions do other sysadmins use for a server replacing one already in existence? It might seem like a silly question but I'm genuinely curious.
