Instead of adding a sandbox hole here, there is a portal for asking users to allow your app to run at startup. Apologies that it's not well-documented yet, but I've filed an issue report against docs with more info and reference material: elementary/docs#159

Hey @danrabbit , I implemented a tweaked version of the code you put on elementary/docs#159 however it only asked me once permissions and I didn't be able to catch the result or anything to debug and adapt the rest of my code to the user's election, and when I triggered the event again the portal dialog didn't show up again. Do you know where can I check the status of the Portal permissions (and perhaps being able to change them to trigger the permission dialog again) and where are stored the desktop files that will run on autostart?

It should appear in System Settings → Applications → Startup and ~/.config/autostart. I'm kind of having trouble working with it myself testing locally, so maybe we shelve this for now. I'll investigate this more, write some good docs, and then let you know!
