summary: Check that mounts are mounted correctly if snapd gets activated
details: |
When booting with basic.target for example, snap mounts are not
mounted. But sockets.target is active, which means snapd.socket
is. If a snap command is emitted, then snapd will start. But it
expects mounts to be there.
