Such standards has already been there for a while, and it's .Appimage file. this type of package can run on most linux distros. And, it's portable, contains all the dependencies that are needed to run the package. Better than snap or flatpak IMO.
Hi oliverjia, As I understand it, packaging Linux system components and distributing the Linux system is quite different than packaging and distributing Linux applications for which .Appimage format was intended - i.e. two different kinds of things, and therefore intended for different purposes while appearing to "do the same thing" that is not actually the "same thing" to make the distinction between the different methods. -- Tom
The difference being that Snap in Ubuntu takes advantage of Apparmor security as Flatpak does via SE Linux in Fedora.
So could I install Flatpak then install firejail and chrome into Flatpak? I'd be running a sandboxed browser in a sand box in a virtual environment. I've got to read about it again.
