This series of patches prepares the way for a later series which will add write support for Windows Registry 'hive' files to our 'hivex' mini library. About hivex: http://libguestfs.org/hivex.3.html About the Windows Registry: Forget it - there are no reliable references. However the Wikipedia page explains some of the top level concepts: https://secure.wikimedia.org/wikipedia/en/wiki/Windows_Registry And this page explains the format, although it is frequently inaccurate (just less so than other documents): http://www.sentinelchicken.com/data/TheWindowsNTRegistryFileFormat.pdf These patches are ready for review right now. I'll post the second series which add write support later this week.
