Comment 3 for bug 1609903

Provided this happened early enough in boot, this could work. As an example of why we need this to be early in boot, on Azure we can't get networking until walinuxagent has run for the first time.

As a side note, how much slower is installation of a seeded snap than boot-time mounting etc. of it? Clouds are very, very focused on boot time at the moment, so that's something we'll definitely need to be sensitive to.
