Any change of getting the guest additions installed with the vbox? Have looked at your ft branch and can't see the additions being installed and is a requirement for inclusion on the vagrant forge. I understand that the additions have to be compiled against the kernel, as we require this on my current project is we set up a pipe line to compile the additions against all kernels and drop them in an S3 bucket, you could do a curl at the end of the kick script to obtain the correct additions to match the kernel?

I would like to reduce our image size as soon as 7.4.1708 is released - it would make downloading the image and instantiating a new box significantly faster, as well as reducing our bandwidth usage (we have 4.5 million downloads so far).  We have to uninstall some packages that Anaconda insists on always installing, but we don't regain the space used by those packages unless we fill the freed sectors with zeros.  On XFS, we can only fill the entire disk with zeros using dd in %post (zerofree only works with Ext4 filesystems, which is what Fedora uses) - writing 40GB of zeros on our CBS builder would already be pretty bad, I wouldn't want to switch to 100-200GB disk images (the disk I/O is actually double that size, since the sparsify process would need to read the image file resulting from the installation).
> Adding another disk to a Vagrant box is a somewhat fragile process, but resizing the existing disk image works pretty well and could be automated, I think. [1]  You could also use Packer to generate customized versions of our official images for you own use - please see the vbox-packer branch in [2].  The latter is fully automated and takes less than 30 minutes on my Mac Mini "late 2009" with only 4GB RAM and a slow mechanical hard drive.
