Easy win: Enable Kea run_script plugin

thermo

I have a fairly straightforward suggestion which is easy to enable and doesn't require any GUI changes.
The reason behind it: I've finally got IPv6 at home for the first time (yes, in 2024!), but it's a dynamic prefix so it's (nearly) impossible to make static mappings, along with the need for DNS to be elsewhere, rather than pfsense be the Lan's DNS server.

I have this working on another system with KEA DHCP + ULA, but since KEA is on the pfsense box itself, it would make sense to enable the DHCP -> external DNS mapping there and have no further need for the ULA. And this will also work for Kea dhcp4.

Enable kea libdhcp_run_script.so (part of the standard install)

"hooks-libraries": [
        {
                "library": "/path/to/kea/hooks/libdhcp_run_script.so",
                "parameters": {
                        "name": "/path/to/kea6_script.sh",
                        "sync": false
                }
        }
    ],

kea6_script.sh would contain something along the lines of:

#pseudo code
for file in `ls /path/to/dhcp6-scriptsdir.d/` do;
   exec file

/path/to/dhcp6-scriptsdir.d/ would contain my script(s), and I could just put something in there which does the DNS update remotely using nsupdate or something more fancy with a cgi script and curl https://mydns.example.com/dnsupdate?host=$HOST&IP6=$IP

Can anyone suggest reasons for not doing this? And how do I get the developers attention?

Turns out it wasn't too difficult to do myself.
