Comment 8 for bug 1884933

I fixed the typo Frank mentioned in the git repo, it doesn't seem worth a new upload.

I made myself an amd64 ISO with an initrd built with casper from proposed and tested a few boot scenarios. They all worked and I observed the desired UX improvements. I also tested the interactive netboot and that worked, although as expected there is a significant delay on amd64 and lots of messages about failing to mount /dev/sr0. We can worry about those in the future!

Together with Frank's testing, I'm going to mark this verification done.
