Cannot install Zulu Embedded in build script

[whymarrh]

Running the build script produces the following error when trying to unpack zulu-embedded-8:

Unpacking zulu-embedded-8 (8.25.0.76) ...
dpkg: error processing archive /var/cache/apt/archives/zulu-embedded-8_8.25.0.76_armhf.deb (--unpack):
 cannot copy extracted data for './usr/lib/jvm/zulu-embedded-8-armhf/jre/lib/aarch32/client/libjvm.so' to '/usr/lib/jvm/zulu-embedded-8-armhf/jre/lib/aarch32/client/libjvm.so.dpkg-new': failed to write (No space left on device)
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

The failed to write (No space left on device) bit leads me to believe that the disk image size is at fault but I'll need to look into this a bit more. This prevents building new images.
