I think that would be dhcpcd, which is also used by NetworkManager.

It turns out we don't package dhcpcd in Fedora.  If we did
the following, would it work?

if grep -sq guestfs_network=1 /proc/cmdline; then
  if dhclient --version >/dev/null 2>&1; then
    dhclient
  else
    dhcpcd
  fi
fi

It seems as if it would, from reading the dhcpcd man page ..

Looks like the syntax is 'dhcpcd <interface>'.

Scratch that. At least in SLED12 dhclient comes from dhcp-client.rpm.
