Checking "Enable Network Booting" under "Display Advanced" and clicking Save doesn't record

<dhcpvdv6> 
   <netboot></netboot>
</dhcpdv6> 

to config.xml thus [[https://github.com/pfsense/pfsense/blob/ed089dc3624c10036bc357c7d40d779a7cc965d6/src/etc/inc/services.inc#L1356]] never returns true.

Steps to replicate:
Enable DHCPv6 Server
Click Network Booting -> Display Advanced
Check Enable Network Booting
Click Save

Notice Enable Network Booting is checked
Click Services -> DHCPv6 Server & RA
Click Network Booting -> Display Advanced
Notice the box is unchecked

I believe this bug also impacts 2.3(.x), I just never got around to reporting it.
