I read it is better than flatpak/appimage/snap.
"Adapting Snap on deepin: Since Snap has many compatibility issues except for Ubuntu, we gave up.
- Converting some of our homegrown apps to AppImage: AppImage has good portability, and these apps can easily be used on other distributions. However, it doesn't have centralized repository storage and package management, and doesn't provide the same level of sandboxing as Snap and Flatpak, so its security can't be guaranteed, and it's not suitable to be used as the default package management method for the operating system.
- In 2017, deepin followed up the Flatpak format and completed the construction of 100+ packages, but did not continue to adapt due to the large size of the application, excessive disk
occupation, slow bug fixing and other reasons. "
Did someone consider it as better alternative for these package formats or is this just "15 standard" for package formats because deepin wanted to make something.
Are there any distros which use it apart from deepin and which is packaged in this format, because I want to drop flatpak because it takes too much space on my system.
I actually didn't know this was a thing. I doubt i'd be interested in using it though. I wouldn't be surprised if this kinda goes the way of snap where pretty much only deepin is going to be using this on their distro. I'm personally sold on the nix/guix way of doing things, but i understand that's not for everyone. In the rare instance that i can't get something to work through guix or nix i like using flatpaks mainly because they work on these distros without fhs-related issues. With appimages for example they often won't run because, eventhough they claim to be portable, they do actually rely on some things being installed on your system.
