Module qubes_dom0_update

[Guiiix]

qubesos.core.qubes_dom0_update

This PR adds a new module qubesos.core.qubes_dom0_update to manage packages on dom0.

New features

Ability to install packages on dom0 with the same syntax as common packages managers modules

qubesos.core.qubes_dom0_update:
  state: present
  name: nano

qubesos.core.qubes_dom0_update:
  state: latest
  name: "*"

qubesos.core.qubes_dom0_update:
  state: absent
  name: nano

The generic package module can be used, but the module name must be specified in the use parameter as qubes-dom0-update is not resolved as the package manager by the system facts (maybe we could try to ask to upstream) ?

package:
  state: present
  name: nano
  use: qubesos.core.qubes_dom0_update

The module can be used to switch audio daemon:

qubesos.core.qubes_dom0_update:
  switch_audio_server: pipewire

How it works

state present

For state=present, the module will check in dom0 rpm db if the specified packages are already installed. If so, the module exits without any change. If the specified packages don't exist, it will call qubes-dom0-update to install them. Then, it will look into the local RPM DB a second time to check the version installed and to provide the appropriate output (for example Installed: vim-enhanced-9.1.1914-1.fc41.x86_64)

### state absent

For this state, the module performs exactly the same actions as the dnf5 module: it will use libdnf to check if the packages are installed and remove them.

state latest

To ensure the system (or the specified packages) are up to date, the module will call qubes-dom0-update without any previous analysis. Then it will rely on command output to now if changes happens. If so, it will look into the last RPM transaction to provide the list of upgraded packages.

param switch_audio_daemon

For pipewire, it will check if pipewire and pipewire-pulseaudio are installed. If so, the module exit with changed=false. If not, it will call qubes-dom0-update --switch-audio-daemon pipewire

For pulseaudio, it will check if pulseaudio is installed. If so, the module exit with changed=false. If not, it will call qubes-dom0-update --switch-audio-daemon pipewire

Closes QubesOS/qubes-issues#10266
