Helper utility for smartos-image-server (https://github.com/nshalman/smartos-image-server) that makes publishing new images a one-line breeze! For the global-zone companion script, see: https://gist.github.com/jasonpincin/4958099

#
#   Helper utility for smartos-image-server
#   https://github.com/nshalman/smartos-image-server
#
#   Global-zone companion script available:
#     https://gist.github.com/jasonpincin/4958099
#
#   This takes an stdin stream (a zfs snapshot), and updates a 
#   smartos-image-server with the files (zfs.gz, manifest.json) 
#   it needs to serve the image.
#
#   Afterwards, it restarts the image server.
#
# Usage:
#   import_image <name> <version> <description>
#
# From the global zone (into an image server zone):
#
#   Stop your zone and create a snapshot of it.
#      vmadm stop <uuid>
#      zfs snapshot zones/<uuid>@image
#
#   Then send the image to the import-image script 
#   located on your image server:
#
#      zfs send zones/<uuid>@image | gzip | ssh datasets.yourdomain.local './import-image <name> <version> "description"'
#
#   Once complete, you can:
#
#      imgadm update

# Configure these variables to match your organization
