[Dextrose] Problem with olpc-os-builder: ZD image of 20 MB

[Daniel Castelo]

With this configuration:

[buildnr_from_file]
suffix=uy
path=uy-buildnr-0.88-1.5

When the version number has three digits the process fail. Seems like the
image name couldn't have more than nine characters.
For example with the image name: os100uy.zd  the process fail.
Its very strange, because I know that many dextrose builds have long names.

















If i change
