I've heard that story before. I once started a job and was told "Sure, this system is a bit touchy, but don't worry about a thing, it's being replaced and won't be needed after next month." My new coworker pointed out that he had been told the same story a year and a half earlier when he joined.
A year later the power supply on the single main server running dontworryitwillbereplacednextmonth blew out and we needed to replace it. Only it ran a very specific version of Netware with a highly specialized database product that nobody knew how to work with any more and even though we had backups it was still next to impossible to even reinstall the base operating system on anything but the original machine. We wound up checking eBay for an exact duplicate of the dead server, raced out to the next city to buy it and then just swapped the hard drives, powered it up and hoped for the best.
It worked, and a quick meeting was held in which my team stressed just how lucky we were to be able to recover from this and that we needed a real solution that didn't involve waiting until next month. The CIO listened to this,nodded his head and suggested that we should try to buy two more replacement servers just in case it happened again.
Another year later, when the company was finally bought up and the office closed down, dontworryitwillbereplacednextmonth was still happily running in the corner of the server room, waiting for a new application that would do everything that it did.
Any month now.
