Ignore my previous message -- Seems my testing was done with INTERFACES
being set in /etc/defaults/isc-dhcp-server... (whoops!)
After reverting my configs/init.d scripts to the originals, and more
thorough testing, I've determined adding the below code in
/etc/init.d/isc-dhcp-server after line 153 in 4.3.4-1 (the end of the
"start" "case" statement) will start isc-dhcp-server even when none of the
"INTERFACES" variables are set in /etc/defaults/isc-dhcp-server:
# If both $INTERFACESv4/v6 is 0-length, determine version to
launch based on
# which version of config file exists
if test -z "$INTERFACESv4" -a -z "$INTERFACESv6"; then
if test -e "$DHCPDv6_CONF"; then
start_daemon "-6" "$DHCPDv6_CONF" "$NAME6" \
"$DHCPDv6_PID" "$DESC6"
elif test -e "$DHCPDv4_CONF"; then
start_daemon "-4" "$DHCPDv4_CONF" "$NAME4" \
"$DHCPDv4_PID" "$DESC4"
