-## gce-disk-expand package for CentOS/RHEL
+## gce-disk-expand package for CentOS/RHEL and Debian
 
-This package is intended to expand the root partition up to 2TB on a GCE VM. It
-consists of several scripts from other packages that for various reasons are not
-maintained by the distros; cloud-utils-growpart, dracut-modules-growroot, and an
-upstream version of the growpart script. See below for details. This package is
-included in GCE CentOS and RHEL images after v20160415.
+This package is intended to expand the root partition up to 2TB on a GCE VM
+without a GPT partition table and over 2TB on GPT partitioned UEFI enabled
+images.
 
-### Build the package
+This package has been tested on the following distros and versions.
 
-A script to build the package is provided for convenience.
-`./build_package.sh /OUTPUT_DIR` will yield an rpm and an srpm in the
-defined output directory for EL6 and EL7.
-
-### Package usage
-
-Install the gce-disk-expand package for your distro with yum and reboot:
-
-* CentOS/RHEL 6: `yum -y install /PATH_TO/gce-disk-expand-el6-VER-DATE.x86_64.rpm ; reboot`
-
-* CentOS/RHEL 7: `yum -y install /PATH_TO/gce-disk-expand-el7-VER-DATE.x86_64.rpm ; reboot`
-
-Your root partition will now be expanded to the full size of your disk up to
-2TB.
-
-#### Growpart
-
-The growpart script used in this package is not from the 0.27
-cloud-utils-growpart package. There are bugs in that version of growpart,
-primarily a bug that doesn't respect 2TB disk partitions on MBR disks. This
-means that if you had a disk that was 2.1TB, you would end up with a 0.1TB
-partition instead of 2TB partition. Obviously, this is bad. The upstream
-[cloud-utils 257 release](http://bazaar.launchpad.net/~cloud-utils-dev/cloud-utils/trunk/tarball/257)
-fixes this bug and others while not introducing more bugs and dependencies in
-further upstream releases of this script. It is therefore not recommended that
-you try to use the [0.27 growpart package](http://rpmfind.net/linux/RPM/epel/6/x86_64/cloud-utils-growpart-0.27-10.el6.x86_64.html)
-from the EPEL repo.
-
-#### Dracut module for EL6
-
-The dracut module is taken from the [dracut-modules-growroot](http://rpmfind.net/linux/RPM/epel/6/x86_64/dracut-modules-growroot-0.20-2.el6.noarch.html)
-package in the EPEL 6 repo. The dracut module allows the partition table to be
-expanded on boot before / is mounted and prevents an additional reboot in CentOS
-and RHEL 6. CentOS and RHEL 7 support live partition resizing by the kernel and
-do not need the dracut module.
-
-#### The expand-root script
-
-The expand-root script is derived from the
-[bootstrap-vz version](https://github.com/andsens/bootstrap-vz/blob/c682dab6ec51767b6e529c1589c5630f6295953a/bootstrapvz/common/assets/init.d/expand-root)
-of this script used for Debian instances. Essentially, it just calls the proper
-filesystem expansion utility to live resize the filesystem on first boot. The
-root partition is hard coded as /dev/sda1 in this script.
