You should avoid running defrag on "shallow" updates as it will cause the updates to become quite a bit larger. It is still advisable to run defrag before publishing the first version of the LivePC or when doing a deep package. Also, it is imperative to zero the empty parts of the disk after defrag and before packaging, using SDelete on Windows or "<code>dd if=/dev/zero of=/foo bs=65536; rm /foo</code>" on Linux. Otherwise, the LivePC will waste space storing duplicate parts of the same file. -John Sat, 03 Nov 2007 19:08:33 -0700 http://www.moka5.com/node/1605 What consequences can have defragging a LivePC, expecially on the streaming functionality of the LivePC Engine? I mean, do you stream only the changes between subsequent releases of a LivePC basing on the differences between (virtual) hard disk sectors, right? If that's the case, when one defrags a disk, a lot of disk sectors, even if they didn't change, will change position, so the Engine will see them as 'modified', and so will stream a lot of unnecessary data, right?
