Hi, I’ve had a similar problem while deploying the image for a ext4 Linux base PC.

// UPLOAD
1)You have to use the Raw Mode (dd) (takes a lot longer ) to Upload the Image

//DEPLOY
1)Setup your machine to Start in DEPLOY DEBUG (HOSTS->BASIC TASKS)
2)After you client starts execute vi /bin/fog

• Goto to line 595,597 and change “gunzip” keyword to “sh /usr/bin/gunzip”
  3)Execute fog, and your deploy should start.

In 0.32 Fog you can upload an ext4 image in dd mode, but, it seems that when you deploy the image the fog script cannot find gunzip (althouth the PATH is defined)

That’s how i’ve fixed, as we speak i’m deploying a Kubuntu image in ext4

Hope this comments was usefull.
