• No obvious security or stability concerns or any regressions observed in testing
• The package was tested against the volatile stream

Additional testing notes:

Still won't build for some silly reason I can't understand #2357

Additional Context

I see we still don't have any firewall, so I think it's a important inclusion for better security.

This took me a while to figure out... You owe me :)

Let me know if anything is confusing.

Oh and we'll need a separate commit for systemd-preset-aeryn, to enable firewalld

@Jaredy899

So I did all the changes and it's working fine, even firewalld-config but firewalld-applet refuses to work:

firewall-applet
Traceback (most recent call last):
  File "/usr/bin/firewall-applet", line 13, in <module>
    from dbus.mainloop.pyqt6 import DBusQtMainLoop
ModuleNotFoundError: No module named 'dbus.mainloop.pyqt6'

I have python-pyqt6 installed and also set it as rundep for firewalld-applet but it doesn't seem to do any effect

[Jaredy899]

There's a comment in pyqt6 about not knowing if we want to enable dbus mainloop support. Maybe try rebuilding that package locally and seeing what comes of it.

[witchlliee]

Enabled dbus mainloop support for firewalld-applet.

[Jaredy899]

Couple more things. Sorry!

[Jaredy899]

I'm going to assign this to Reilly to approve considering how substantial this package is.
