[Live-demo] disc space

[Angelos Tzotsos]

I think that the problem is that tmp disk space is also included in each
step.
So if an application downloads much data in /tmp and does not clean up
(because the setdown.sh will clean /tmp at  the end), the size goes up.
Remember we do a df in chroot so we get all the host filesystem info (the
build server does not do anything else during build)

Perhaps a du -sk /tmp before and after each package installation would help
determine how much data are actually installed (/tmp excluded)
