From 124deec9ae2a92637490c616d0f91e3e369687bc Mon Sep 17 00:00:00 2001 From: Gerard Ryan Date: Tue, 19 Nov 2019 22:39:51 +1000 Subject: [PATCH] cache-domains: Changed to hotplug script Since we have to restart dnsmasq to reload the config anyway, this package doesn't need to run before anything. We do however need to wait for the network so I've changed this service to be a hotplug script and utility script.
