We need to think hard about this one, we have a couple of conflicting 
interests here with the amount of space.

The Poky distro and core-image-sato are examples of for the community 
and developers to use, we want to set good examples where ever possible. 
One of the intentions of core-image-sato is to show a compact image with 
a graphical user interface, so having a minimal, but usable amount of 
free space is important. We don't want someone new to look at this and 
see a large image as it might put them off the project without 
understanding the tune-ability. This is an embedded environment, not a 
desktop with a large disk, we want to share that message.

Another goal of the Poky distro is to create something that is testable 
and automated testing is important part of this.  I read the bug report 
and commented on it as well.  Is there a way to clean-up after the 
tests?  Are single tests consuming the 100M available? Is it slowly 
accumulating tmp space?

What other options can we do here?  Do we need to consider a different 
image for testing?  Or build 2 images similarly one with extra space?

We need to think about the different scenarios and usage.

Thanks
