From 459ed6759a307b389f6ec1874136ec9aa0749120 Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Thu, 19 Jan 2012 10:32:09 +0000 Subject: buildhistory: record additional image info Record some additional information about images - the uncompressed size of the final image as well as the values of various variables that may have influenced its contents. This is recorded in a machine-readable "image-info.txt" file similar in structure to the package history files. Also add some code to analyse changes to these values. (Most of the variable values aren't monitored directly but will be used as contextual information when they change at the same time as the content of the image changing.)
