Yes I'm aware and of course we'll test a specific commit and stick to it 
if it works :)


I'm trying to wrap my head around the new way and after studying 
mods-config/sql/ippool/mysql/queries.conf a bit more, would it be 
something along:

1. create a copy of mods-available/sqlippool (fe. called dhcp_sqlippool) 
and set:

   - allocated_address_attr = dhcpv4.Your-IP-Address
   - owner = "%{Vendor-Specific.ADSL-Forum.Agent-Remote-ID}"
   - gateway = "%{dhcpv4.Gateway-IP-Address}"


2. in sites-available/dhcp determine pool name and run dhcp_sqlippool to 
allocate an IP address:

         &control.IP-Pool.Name := "determine pool name with some custom 
logic"
         if (!&control.IP-Pool.Name || &control.IP-Pool.Name == '') {
                 do_not_respond
                 return
         }
         dhcp_sqlippool


3. In sites-available/dhcp Request processing section set:

         if (ok) {
                 &reply.Your-IP-Address := &Your-IP-Address
         }
