That's odd... The whole process defbitely works if you have much less
then 4GB of disk space, and I think our current autobuilder has 30GB.
What data was written to where, can you find that out? And which
filesystem are you using? I assume you are running either PureOS or
Debian Testing on the host system.

You only need ~500MB to store a compressed root filesystem image, then
some space to decompress it and the amount of space to build the image
and space to store the resulting image. That should never fill up 77GB
of space (and I built it with less then 4GB free on my local machine
once).
