The Flatpak is already packaged and works well. It just needs to be maintained from a person that joins the Inkscape community.
This would allow further improvements like Portal support and making the app official on Flathub.
Update: One might have been found!
I do mean downloading random stuff from random websites.
Hmm, is that a feature or a flaw?
A matter of perspective I think. It’s a flaw in my opinion. Just downloading anything from anywhere sets one up for failure/malware.
Code Signing on its own is useless, I think. If there is no distribution structure or user-validated trustchain, of course. But then you don’t really need Code Signing, a simple hash is enough.
My personal preference are the distro repos, to a point where I even dislike additional package managers like pip, npm or cargo.
Reducing the size of the OS helps a ton here.
And mounting home read-only. I think Android and ChromeOS do that. I will experiment with that too, it is really interesting. You mainly need a different place to store user scripts, and appimages are broken (how sad), the rest should be fine.
Then a few more core concepts help too:
Flatpak helps a ton centralizing the packaging efforts. And it works. There are tons of officially supported packages. And I guess many of them will be maintained upstream.
But you still have a secure system, sandboxing, verification and packagers that keep an eye on it, kind of.
On a secure system you would need to pay a lot of people, like the typical 3-5 people that package most apps. For doing security analyses, opting-in to every new update etc.
I’m sorry, I don’t think I can see the point you are making. Are you saying that one can get around the 3-5 people by using flatpaks, ro home directories and other mitigations?
What people?
Nonexecutable home directories I mean. /tmp too. This only makes sense as normally programs are in different areas. I will experiment with that.
