Please Explain: qubes-menus And qubes-desktop-linux-common | Minimal Templates

I am a big fan of Qubes Minimal Templates (Fedora and Debian) and have been using them for years. I am quite familiar with them to the point that most of my VM templates and standalones are minimal ones. However, I have never been able to figure out what these two packages do:

  1. qubes-menus
  2. qubes-desktop-linux-common

Please explain to me what their purpose is.

Thanks for your amazing help!

see the ‘Description’ field of the following commands:

You also got these infos in the github repository:
https://github.com/QubesOS/qubes-desktop-linux-common/blob/main/rpm_spec/desktop-linux-common.spec.in

These packages are installed in dom0, not in the templates (minimal or not).
(You can confirm this with: sudo dnf list --installed, in dom0 and in the templates)
