The point is that you should be highlighting your Linux skills for a company that is seeking someone with Linux capabilities.

Applying to a Java shop? Same deal, highlight your Java capabilites and projects. Instead, you are highlighting nothing.

Another issue is that you have been out of work for a long time. I can't find a reference right now, but being out of work reflects poorly on you.

Perhaps you could fill that period in with "Freelancing?"
