summary: Run test to ensure snaps can store data on ubuntu-save partition
details: |
This test verifies that a folder is created for newly installed snaps on the
ubuntu-save partition. It then verifies that we can write data to that folder
and that the folder is removed again once the snap is removed.
systems: [ubuntu-2*]
