Can DHCP and DNS both use .local on the same LAN?
Multi tool use
My local LAN machines are assigned IP addresses from a Fortigate 60D DHCP server.
The DHCP uses .local as its domain name.
I now started a DNS server, also running off the Fortigate 60D.
I'm reluctant to set the DNS domain name to also be .local, as it seems to me that this may cause clashes.
Am I being paranoid, or is my apprehension justified?

That depends on the Fortigate management software, if you can set it to return your DNS server's IP address with the DHCP return answer. This might require giving it a static IP address. The Fortigate manuals I can find on the Internet don't have the necessary info.

There is no problem with DNS and DHCP using the same domain name. But the name .local is special; it is reserved for mDNS and you should not configure a DNS server to use the .localTLD. From RFC6762:
This document specifies that the DNS top-level domain .local." is a
special domain with special semantics, namely that any fully qualified
name ending in ".local." is link-local, and names within this domain
are meaningful only on the link where they originate.
