How Snappy packages are different from Deb
An article from PCWorld. Skype, Spotify, Minecraft, JetBrains Dev Suite, MySQL Workbench, Blender.
- Applications are no longer installed system-wide. The base Ubuntu operating system is kept securely isolated from applications you install later. Both the base system and Snappy packages are kept as read-only images.
- Snappy packages can include all the libraries and files they need, so they don’t depend on other packages.
- An update can never fail, as a package installation could potentially fail and become incomplete with typical Linux packages.
- Snappy also supports “delta” updates, which means only the changed bits of the package need to be downloaded and installed.
- Snappy-based Ubuntu systems might be standard.
