summary: Basic verification of socket-activated services.
details: |
This installs a snap which define sockets for systemd socket activation, and verifies
that basic start/stop works as intended for services that have socket activation.

# although classic snaps do not work out of the box on fedora,
# we still want to verify if the basics do work if the user
