It is not possible to troubleshoot network module loading without
pciutils. Although it is a troubleshooting tools, it is not
troubleshooting the network, but to make the system itself be able to
load kernel modules and reach the network, therefore necessary.
Qubes that have the updates-proxy-service enabled will have the
repository definitions set to work with the proxy, being it a TemplateVM
or another type of qube. Qubes that have that same service disabled and
are based on templates that are being cached, will have the repository
definitions corrected for it to work like normal systems via the
networking instead of caching proxy.
Optimizations were done for a faster runtime, previously it would call
sed 38 times on Fedora-39, now it only calls sed 2 times for Fedora
repositories (one extra for rpmfusion) and some more for PackageKit and
dnf.conf markers. Inexpensive runtime is a must for a script that may
run multiple times, such as when being called by a tool monitoring the
filesystem such as inotify.
Code from /usr/lib/qubes/update-proxy-configs was used for the NetVM use
case of the cacher, thus the license had to be changed.

Very useful for template based qubes to uninstall the cacher definition
to reach remote repository definitions with direct connection.

Updates happens multiple times, normally 2 to 3, even if we consider a
state without includes. On states with multiple includes, it could
easily get approximately 10 updates being ran. This behavior leads to
unnecessary network bandwidth being spent and more time to run the
installation state. When the connection is slow and not using the
cacher, such as torified connections on Whonix, the installation can
occurs much faster.
Adding external repositories has to be done prior to update to ensure it
is also fetched.

Provided in the default Dom0 installation as it brings a much better
usability and small packages.
KDE ships with kdialog but without a screenshot utility.
Xfce ships with xfce4-screenshooter but without a dialog utility.
Scrot and Zenity are minimal tools that works on both DEs and are very
small packages.

Git revision is specified in the git module to Salt not fail trying to
verify it is in HEAD when it is in a tag from a previous installation.
Fixes: https://github.com/ben-grande/qusal/issues/27
Comparison to upstream:
- POSIX compliant;
- Add more dialog tools: kdialog;
- Add more screenshot tools: spectacle, xfce4-screenshooter;
- Change work "Nautilus" to "File Manager";
- Fix all shellcheck messages;
- Fix wording of confusing options seen by the user;
- Fix variable names without meaning;
- Remove commented/unused code;
- Remove extraneous messages sent to the user;
- Remove Imgur support; and
- Remove ImageMagic, use tools that support editing: spectacle.

A Minimal Fedora template can't be the management qube or the targeted
qube of Salt as it is missing dependencies that are only available in
the full template. The management qube is temporarily changed to the
non-minimal version so the minimal template can be targeted once and
then it takes over the management disposable template.

- End qrexec policy with deny rules;
- Move the USB setup from sys-audio to sys-usb; and
- Document the pros and cons of the different types of USB devices
assignment to client qubes or to the server.
The target of qubes.ConnectTCP has 'socat' because it is a dependency of
qubes-core-agent-networking. In case the target has not networking
packages, this needs to be taken care by the formula that creates the
target, not from the client itself.
Split-mail allows to separate the receving, reading/composing and
sending of mails to separate qubes, while having the reading/composing
qube offline and a manual step necessary to authorize mails to be sent
form the sender qube.
Depending on OEM will conflict the state IDs because they are the name
of the qubes being created. As not much changes are needed and we
customize much more, stop depending on upstream.
The client should install the agent client packages and not the
opposite. The way it was, it would not be possible to include the agent
client packages to the ssh client, as it would create a recursive loop.
The mixer provided by the program volumeicon is okay, it shows only one
input and one output. Pavucontrol correctly detects the different inputs
and output of each audio client, you can have deeper control of the
client volume.
As it is not easy to get files to dom0 and we don't want to reimplement
a package manager, crude Git is the solution as of know.
With Git we have the following advantages: native fetch format for
source controlled files, cleaner command-line, automatic signature
verification during merge, the disadvantage is that it is not included
by default in Dom0 and filtering it's stdout chars are not possible.
Note that the remote can report messages to the client via stderr, which
is filtered already, and if it tries to send an escape sequence to
stdout, the operation will fail with 'bad line length character: CHAR'
printed to stderr on the client, unfiltered by qrexec, but filtered to
some extent by the git client. If it is an escape character, the char is
transformed to "?", but UTF-8 multibyte characters are not filtered. Up
to 4 bytes can be displayed.
Tar on the other hand is already installed, but it is much ancient and
it's file parsing caused CVEs in the past relatively more drastic than
Git, it also doesn't only include committed files, it can include any
file that is present in the directory, which by far, increases a lot of
the attack surface unless you reset the state to HEAD, clean .git
directory manually and there are possibly other avenues of attack.
If persistent rules are chosen, it can deal with disposable sys-net, but
not with disposable sys-firewall, as the qube ip will change, the rule
won't work. Applying the rule to the disposable template is a "try it
all", but it's usage is discouraged.
The removal was first implemented to get a clean state of the qube, but
there are side effects, it fails if the user created a named disposable
based on the dvm and also removes the (dvm) entry from the appmenu.
The sys-usb case is a workaround in case the user selected a
non-disposable, an appvm sys-usb during system installation.
- Passwordless as it doesn't compromise security;
- Firewall blocks access to the interface in case the pihole is exposed
to the internet;
- setupVars.conf needs to be 644 for non root commands to the pihole
script to work, so the WEB_PASSWORD can be read as normal user,
restricting root on pihole does not make sense, as it can modify the
network setting via pihole web interface.
- Default sys-net and sys-firewall to disposable;
- Set global and per vm preferences by starting the qubes or shutting
down them when necessary; and
- Less manual steps remaining for the user: just rename the net qube, as
it can only be done via Qubes Manager.
