	* Fix a bug in the way snf-image-update-helper reads the links of the
	  kernel and the initrd in the helper VM.

	  user can see the program's command line by using ps.

2012-09-15, v0.6
	* Fix import and export scripts
	* Add new config_url os parameter. This can be used by snf-image to

	  snf-image can output progress and error messages to external programs
	  when running.
	* Make the name of image properties case insensitive

	  non-empty value
	* Remove --enable-pithos-backend option in configure. This will be
	  detected at runtime
	* Create package list in snf-update-helper every time debootstrap is
	  performed. If a cache file is found, snf-update-helper will use this
	  list to determine if it is OK to use this cache file or not.
	* Add mechanism for overwritting the helper's Unattend.xml file

2012-03-29, v0.3.6
