- EdgeOS code in documentation wrong?

Using the code in the documentation throws an error.
I am running Edgerouter 4, I did not want to change the documentation as I don’t know if it is the same on all EdgeOS routers or just the ER-4.

set service dns forwarding options \"dhcp-match=set:bios,60,PXEClient:Arch:00000\"
Cannot use the double quote (") character in a value string
Value validation failed
Set failed

The error is thrown on all commands containing \.

Removing the escape char \ solves the problem.

config.boot gets a line like this after removing the \:
options dhcp-match=set:bios,60,PXEClient:Arch:00000

Should the documentation be changed?
