In the production environment, few companies use Linus. The reason is that people still lack trust on Linus. If a company
needs support for linus, it usually does not know whom to contact. But things will be changing---IBM has decided to push Linus.
IBM asks all of its products be able to run at Linus. It is a credit for you to be able to play with Linus, but do not overstate it as you hunt for jobs.
