Hi Laurentiu, have you had a chance to look at the xfs issue around
zerofree?

Anyone reading this thread opposed to using ext4 on the Vagrant images and
care to share your concerns? From my perspective, the entire purpose of
Vagrant is to provide a (reproducible) development environment for
application developers that shouldn't be concerned with the filesystem in
use outside of some edge cases. If ext4 gives an easier way to shrink the
image size, and it sounds like it does, why not use that by default here?

Is it possible and worth creating a "7-minimal" vagrant image in addition
to the default one currently built? For my needs, minimal (with a larger
partition!) would be perfect because I just want a small, standard CentOS
image that can then be configured with whatever config management system to
prep it for development.
