Yeah, I thought that too because we had talked about this earlier. So, I
did it all again.

I booted the Dragora live system, using the image available at

http://rsync.dragora.org/current/iso/beta/dragora-3.0-i586-beta1-live.iso

Then, I used fdisk on that live system to partition the hard drive.
Here's the record:

Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Oh, I somehow missed that “package” meant “a package installable with
qi” in this case. Here's a more detailed explanation of what I did
instead, just for clarification:

* downloaded the package and checksum file
* verified the checksum
* decompressed the package
* extracted the tar archive
* put the contents of the tar archive on a USB key
* plugged the USB key into the machine running the live system
* used rsync to transfer the files from the USB key to the live system
  as described above

I'll use `qi -u` from now on.
