[Kea-users] Set boot-file-name option based on DHCP client mac-address

[Kristian Pedersen]

Hi KEA list,

I'm attempting to mirror this ISC DHCP construct, where the 
bootfile-name is set based on the DHCP client mac-address:

subnet x.y.z.0 netmask 255.255.255.0 {
     ..
     pool {
         ..
         option bootfile-name = concat(
             suffix (concat ("0", binary-to-ascii (16, 8, "", 
substring(hardware, 1, 1))),2),
             suffix (concat ("0", binary-to-ascii (16, 8, "", 
substring(hardware, 2, 1))),2),
             suffix (concat ("0", binary-to-ascii (16, 8, "", 
substring(hardware, 3, 1))),2),
             suffix (concat ("0", binary-to-ascii (16, 8, "", 
substring(hardware, 4, 1))),2),
             suffix (concat ("0", binary-to-ascii (16, 8, "", 
substring(hardware, 5, 1))),2),
             suffix (concat ("0", binary-to-ascii (16, 8, "", 
substring(hardware, 6, 1))),2)
         );
         }
}

How can I achieve something similar using KEA? We use this for per 
modem/cpe configuration-files for docsis and other types of devices. 
Defining a host entry for every modem/cpe is not really feasible.

I tried a construct similar to this, but could not get it working:

"subnet4": [
     ..
     "option-data": [ {
         "name": "boot-file-name",
         "data": concat('foo', 'bar')
     } ]
]

Kind regards,
