Subject Re: why system.vm.use.local.storage?

Well, certainly you don't want system vms using local storage by
default. How would you live migrate them for host maintenance? I
assume you mean that when you set up a zone and check 'local storage',
and it pops up the big long thing stating "make sure you set the
system vms to local as well in the global config", that pop up should
not exist and happen by default. But the user has already selected
local storage in that case.
