It is probably not clear what I meant with the message.

It is not necessary to use dnsmasq. Just the proper configuration in
isc-dhcp-server. If the vendor encapsulated option is missing, the boot
process do not continue. When the configuration option is present the boot
sequence continues.

root-path must point to the boot directory, so that Rpi can find the boot
files.
