+# Privacy settings #
+####################
+
+# To enable privacy settings, set enable_privacy to 'true' and supply
+# the right name of the wired internet interface that may or may not
+# be connected to the internet so that its MAC address can be spoofed
+# at startup.  Additionally, x200-my will delete /etc/dhcpcd.duid,
+# which will make dhcpcd generate a new DUID-LLT based file with an
+# updated timestamp and the link-layer address of the network
+# interface that is connected to the DHCP device at the time that the
+# DUID is generated.
+
+# IMPORTANT NOTICE: As dhcpcd uses ANY ONE network interface that is
+# connected to the DHCP device to generate the DIUD-LLT file, the
+# wireless interface MUST have its MAC address spoofed as well.  To
+# make wpa_supplicant handle this, add the following two lines in
+# /etc/wpa_supplicant/wpa_supplicant.conf:
+# mac_addr=1
+# preassoc_mac_addr=1
+
+# Finally, it is advisable to set the hostname to "localhost" and have
+# "hostname_short" in /etc/dhcpcd.conf so that the actual hostname of
+# the machine should not be sent to the DHCP server.
+
+enable_privacy="false" # either 'true' or 'false'
+wired_interface=""     # supply the actual interface name! In case of
