You may still be using an old version of installSeed.py but a new version is now available from my Github Repository. I don’t have a lot of time right now, so let’s start with the output of the script:

Note the much improved output. Which is way more informative. Now you know what you’re about to download.
It now also asks you if you want to continue. Before it adds the URLs to the download queue. As in multithreaded downloads. To speeds things up.
I also added (the initial) support for seed updates and single package downloads. Like for example FirmwareUpdate.pkg – though this feature will only be available in a next update!
Edit: The text: “Select a target volume for the boot file” should have been: “Select a target volume” and will be corrected in a next update!
