Did you use this instruction? If so, i think you forgot this step
wget -O- https://download.opensuse.org/repositories/home:/bgstack15:/aftermozilla/Debian_Unstable/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/home_bgstack15_aftermozilla.gpg
Can you share a content of /etc/fstab file? It is the first place I would check in your situation.
I try some tests based on your description, and I think I got a solution. Try to use host_vars
This is a playbook:
---
- name: Test for lemmy
hosts: your_hosts
vars:
networks:
ext:
ipv4: "127.0.0.1"
tasks:
- name: Use template
ansible.builtin.template:
src: test.j2
dest: "/etc/iptables/rules.v4"
owner: root
group: root
mode: "0644"
This is a template file test.j2:
{% for rule in rules %}
{{ rule }}
{% endfor %}
This is a host2.yml file in a host_vars directory:
---
rules:
- "-A INPUT -p tcp -s {{ networks['ext']['ipv4'] }} --dport 6000 -j ACCEPT"
For another hosts you can create separate host files with variable rules.
Which module do you use for inserting the template?
Install tlp for better battery performance.
sudo apt install tlp tlp-rdw
You can try Firejail
sudo swapon /dev/zram0
