Description:
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!
