I'm a software architect the long way round, by way of system administration, then configuration management, then devops, then software engineer. Also a fiddler, photographer, and family man.
Many years ago, I was a systems admin who was tasked with maintaining (among other things) an email server. The server was running Debian Linux for its OS, and Exim 3 for mail. Like an idiot, I figured that upgrading to Exim 4 would be no biggie, despite the many warnings that accompanied the release, and blithely went and apt-got it.
A couple hours of panicked hackery later and I'd finally managed to restore service back with Exim 3. Eventually, I got a very nice setup going on the cheap with virtual users in a mysql database,on Exim 4. But I never skipped past a warning like that again without doing my due diligence.
