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!
