* Add/update code comments * Change resolver check to test for pi.hole * Make resolver check timeout after 10 seconds * Use > instead of &> where appropriate * Make resolver check sleep for 30 seconds (effectively waiting up to 50s for dnsmasq to be resolvable) * Provide confirmation upon success of resolver check availability * Quotes and Braced remaining variables as appropriate * Removed duplicate local
