One of the main selling points touted by many Linux-oriented vendors is stability. Once a customer buys a subscription for an "enterprise" Linux or embedded systems product, the vendor will fix bugs in the software but otherwise keep it stable. The value for customers is that they can put these supported distributions into important parts of their operations (or products) secure in the knowledge that their supplier will provide updates which keep the system bug-free and secure without breaking things. This business model predates Linux by many years, but, as the success of certain companies shows, there is still demand for this sort of service.

I wrote once that I wanted to be a tech analyst when I grew up, because no one seems to expect them to get their facts right. That, I reasoned, would make it an easy gig. I could lean back in my chair, put my feet up on the desk, and just make things up. Why research? And people would actually print it as if it were true. And next time they wanted to know something, they would call me up again, even though I called it completely wrong the last time, had huge gaps in my knowledge, got random but truly vital facts utterly wrong, and said the opposite of what is observably true.
