# Note: File should be set to be immutable (`chflags uchg mdns_kill`) after first setting root as the owner (so the file can't be made mutable without root access) - Otherwise, the script could be edited to include whatever and it would still be allowed to run as root via sudo w/o password due to the inclusion of the file in /etc/sudoers

# File specified in /etc/sudoers to be allowed to run with sudo w/o a password. (aka this file itself. Explicit path just b/c of required visudo setup with the same path)
