As mentioned https://github.com/appium/appium-geckodriver#usage that platform name should be either mac , linux , windows but while running on linux getting error

On diiging found that appium soucecode doesn’t include linux https://github.com/appium/appium/blob/a5c6f1c80e031679b16cea2d92fc45281223975f/lib/appium.js#L14
Have tried passing tizen and mac on linux just for sanity and they didn’t work.
