setuid helper program for setting up the local DNS


resolvconf-admin deals with setting the local DNS information, which needs to be done by root on some systems. For example, it should enable a non-privileged DHCP client to add information about DNS resolvers it discovers.

If /sbin/resolvconf is present, it is invoked as root with the recommended data. If it is not present, then /etc/resolv.conf is overwritten with a simple file.

Note: setuid binaries like resolvconf-admin are additional attack surface on your system. If you can use a different approach, such as enabling systemd-resolved, you should probably prefer it.

DO NOT INSTALL THIS PACKAGE (or any other with a setuid binary) IF YOU DO NOT NEED IT!
