[Dnsmasq-discuss] multiple dhcp-options with the same tag

[Wink Saville]

I'm learning dnsmasq and I'm taking advice from ChatGPT-4, probably a
bad idea but so far it's given reasonable advice :)

Anyway, in this instance I was asking a question[1] about how to
configure dnsmasq on OpenWRT.

The first prompt was:

"Using Luci on openwrt is there a way to set a dhcp-option and use it
on a dhcp-host record?"

It answered correctly that using luci you can't do it but you can do
it in /etc/dnsmasq.conf and gave an example:

```
dhcp-host=00:11:22:33:44:55,set:myOptions,192.168.1.100
dhcp-option=tag:myOptions,option:dns-server,192.168.1.2
dhcp-option=tag:myOptions,option:router,192.168.1.1
```

My second prompt ends with the question:

"Anyway, your example shows that myOptions is composed of two separate
dhcp-option's. Are you sure that is legal, can you provide me with a
link or a quote from the dnsmasg.conf documentation?"

Its response was, as is typical. a long winded yes and it also gave me
a quote from the documentation. Of course, I couldn't find that quote,
which is also typical, it lies! Anyway, to cut to the chase I'm
writing because the technique the bot showed does work, at least it
seems to work for me on OpenWRT with dnsmasq v2.86. But, as I said I
don't see in the documentation. Did I just miss it or should I not use
it or maybe it should be documented?
