[HelloNurse]

Is there a written explanation of the "Flatpak Next" plan? What is it supposed to change, and what does it need from systemd?

The article contains only a vague half paragraph of architecture:

  > they want to move the permission management from Flatpak into the service layer, through a new service called systemd-appd. Systemd-appd gives applications an identifier and stores their permissions, and then this data can be queried by the rest of the system. In turn, this enables a slew of other features, not least of which is subsandboxing. 

At first sight this "new service" seems single purpose enough to get a satisfactory and relatively simple standard specification and multiple implementations with or without systemd: what am I missing? Conversely, isn't depending on future systemd developments rather than current features strangely aggressive?

And what other speculated Flatpak features introduce other dependencies from systemd? Discussing whether unwanted dependencies can be made optional or eliminated requires technical details.
