I plan to add a mail gateway using Postfix, ClamAV, amavisd-new and SpamAssassin as well to protect the tender underbelly of our MS Exchange server. However the machine is running 5.1-RELEASE. It shouldn't be. :) I would like to rebuild the machine completely to exercise the knowledge I have gained re: FreeBSD but I can't afford for it to be down for the length of time it would take and I don't have a standby machine available. So what I'm thinking is that I could take a spare hard drive home and pop it in one of my own machines, install FreeBSD on that, and then bring it back to work and swap the hard drive out with the one in the production machine. What kind of problems am I letting myself in for if I go ahead with this? The hardware in the two machines in question is quite dissimilar. For example, one's an Athlon 266 with 64MB of RAM, one's a Pentium[-something] 300 with 400 MB. Here are the things that occurred to me: One of them has an 'rl0' NIC, the other 'dc0'. So I'd have to change the ifconfig_ line in /etc/rc.conf. But would this also imply changes elsewhere that would have to be made? Actually, that's all I've thought of so far. Are there any gotchas I should be considering? -- Danny MacMillan
