Well perhaps it should be a checkbox on the first zone wizard page, have it show up when the user selects 'use local storage'. it could say 'allow system VMs on local storage'.

I just find it annoying setting up a zone with local storage that I have to turn this setting on. If I have no shared storage, then system VMs won't deploy with out this parameter. It's just seems like a useless setting that might have been added because there is something else in the system that isn't working right.
