This adds the disk information utility as a package. 'di' is a disk information utility, displaying everything (and more) that your 'df' command does. It features the ability to display your disk usage in whatever format you prefer. It also checks the user and group quotas, so that the user sees the space available for their use, not the system wide disk space.

Add package for xz-utils (5.2.3)

Adds xz-utils (5.2.3). CrOS dev tools provides these tools primarily for reducing the size of image files to preserve what little disk space we have available on our tiny eMMC drives. For those who don't wish to run dev_install this will allow you to work with xz archives.
