Comment 7 for bug 1790094

At least for now, I can't see of a great solution to the problem but I think I understand what it is. The option is not provided, as I said, if anything is mounted. Well, a feature of all of the Ubuntu images is that they automount swaps in an attempt to increase available memory. The solution is to `swapoff` those before running the installer. There's been a discussion about unmounting everything, or at least swaps, but even both of those are contentious issues. Still, I made a comment on an upstream bug. We'll see what happens.
