snapcore is the umbrella team name on github under which all snap project related sourcecode lives (snapd, the core snap … and well … the core18 snap)
The core snap is the execution enviromnent inside which snaps get run when using them on a classic distro installation. At the same time it also serves as a root filesystem for the UbuntuCore images. The current core snap is built from 16.04 packages. Once the core18 snap is out of experimental stage you will be able to:
- Define something like “base: core18” in your snapcraft.yaml so that your snap builds and runs in the context of 18.04 binaries.
- Have an UbuntuCore 18 image where the core18 snap is used as root filesystem (similar to todays core usage).
