This post takes me back to 2006.

I worked for a meat works that had Sunrays on all the corporate desktops and the IT manager (in a department of 3 supporting a billion dollar business) made the decision to move Sunrays off the clunky Solaris 10 CDE onto... Ubuntu Dapper Drake. My predecessor had worked out how to get all the bits running and we had Ubuntu on Sunray!
