Change domain "local" in avahi and and use a hostname with multiple labels

Question

I need to publish multiple addresses for the same IP (eg: address1.local, address2.local)

Did it creating a service /etc/systemd/system/[email protected] with the following:

[Unit]
Description=Publish %I as alias for %H.local via mdns

[Service]
Type=simple
ExecStart=/bin/bash -c "/usr/bin/avahi-publish -a -R %I $(avahi-resolve -4 -n %H.local | cut -f 2)"

[Install]
WantedBy=multi-user.target

Then if I run: sudo systemctl enable --now [email protected] sudo systemctl enable --now [email protected] It works perfect.

But now if I need to extend it to publish eg: address1.something.otherdomain I have error publishing. Tried different ways, changing the avahi-daemon.conf for example and didn't work for me.

I will appreciate any help you can give me.

Kind regards

EDITED: Using this solution: https://github.com/george-hawkins/avahi-aliases-notes I can handle the use of multiple labels on the cname. But still without being able to change ".local" by something else.
