Update occurred after jailbreak about rootmyroku HOT 1 CLOSED

It blocks pretty much all of them: https://github.com/llamasoft/RootMyRoku/blob/main/server/setup.sh#L107-L114

Unfortunately, I've noticed that the DNS blocking at the device level isn't 100% perfect. The primary issue is that /etc/resolv.conf is a symlink that points to /tmp/resolv.conf which is a world writable temp directory. The startup script changes the resolv.conf file to use the blocking DNS server, but if your network connection status changes (e.g. network blip, restart WiFi, etc) then the resolv.conf file gets reset to the default DNS servers from your router's DHCP config. The DNS blocker runs in a loop every 5-15 minutes, but that may potentially leave you exposed for a time.

Your best bet is to update the default DNS servers on your router as a failsafe. If you don't trust using dns.rootmyroku.com for your whole network, I'd suggest setting up a Pi-Hole and blocking the appropriate domains.

For the time being, I've updated the resolv.sh script to monitor the config file more closely and reset any changes within a few seconds. This should hopefully prevent accidental updates. Apologies for not noticing this issue sooner. Roku inadvertently helped me by banning my devices which prevents them from receiving updates even when DNS filtering fails.
