This is Pi-hole.
It blocks advertisements and internet trackers by providing a DNS sinkhole.

The package will create a new standalone qube, sys-pihole.
It is a drop in replacement for sys-firewall.
Sys-pihole is attached to sys-net.
If you have sys-firewall as the default netvm, this will be changed to sys-pihole.
The installation will try to move all qubes with netvm of sys-firewall to sys-iphole.
sys-firewall will *not* be removed, so you can still use it for some qubes if you want.

 If you want to use Tor, then you should reconfigure your system like this:
 qubes -> sys-pihole ->Tor-gateway -> sys-firewall -> sys-net

You can clone sys-pihole.
If you do you must manually change the IP address of the clone.

Pi-hole will be installed with these default settings:
 The DNS provider is Quad9 (filtered, DNSSEC)
 StevenBlack's Unified Hosts List is included
 The web interface is availble at http://localhost/admin
 Query logging is enabled to show everything.

You can change these settings by logging in to the admin interface at http://localhost/admin
The default Admin Webpage login password is UpSNQsy4
You should change this on first use, by running:
`pihole -a -p`

Removing this package will only remove the salt files from /srv/salt.
It will NOT remove the sys-pihole qube.
It will NOT change Qubes networking.
You will have to make any changes as you wish.
