tsamsoniw writes "IT professionals with Linux chops — particularly systems administrator — are in high demand and short supply, according to a new survey from Dice. Over 90 percent of hiring managers surveyed said they plan to hire at least one Linux professional in the next six months — though nine out of 10 respondents also said that it's "somewhat difficult" or "very difficult" to find experienced Linux pros. That demand — driven by trends such as open-cloud development, Big Data, and increasing migration to Linux — has helped push the average salary for Linux pros up 9 percent to this past year, to $90,853."
