I don't know if it's hugely useful info, but 'No content to install'
means the startup file couldn't be found. This often happens to me
because the startup file location is relative to the directory
containing the image, not the location where you run the command.

So if you're in /home/frank/squeak-ci/ and you say "$
target/cog.r2766/coglinux/bin/squeak target/TrunkImage.image
HudsonTools.st", "HudsonTools.st" is translated into
"/home/frank/squeak-ci/target/HudsonTools.st", not
"/home/frank/squeak-ci/HudsonTools.st".
