I just noticed that the current update of the distribution I'm using (version 18.3 of Linux Mint) boasts supports for "Flatpak". So, I ddg'ed it and found this Wikipedia page about yet.
So I understand Flatpak is some sort of sandboxing framework - but I don't see anything which suggests why it's useful and interesting for me to run all sorts of apps in "isolation" at all - unless I'm managing some physical machine offering "cloud" services. Why would I want to do this?
Going on the Flatpak website, it seems like it's offering a sort of a bypass around the individual distributions' package management system + support for multiple versions of the same package. Now, the second feature I like, but isn't it just something that distro package management systems need to start supporting better? As for the first part - it sounds like the 14 competing standard situation from xkcd. Am I misunderstanding something here?
PS - How is it different than Docker, which also does a sort of a sandboxing that's not as strong as putting up a virtual machine?
