This post of @ben79 even if originally not stricly addressed to the @Testers group, may provide some food for thoughts.
Regardless if you run ROME or Cooker, as om-welcome is one of our jewels ( 
) you may want to test it and check all the modules of all the pages/tabs.
They should properly install the relevant application or open the relevant systemsetting or web page.
I should have mentioned earlier, but I do right now, that you can test the system/s also in virtual machines.
Unless the purpose will be to test hardware and hardware related stuff, of course.
They have some sort of limitation, however virtual machines are good to install packages that you normally would not use in your daily driver box.
