Hi all,

 sorry for the image but some numbers should be displayed in a proper
form. I continued to work on the building optimization of ISAR and the
results are quite interesting. Almost 2x with some great achievements
in some specific areas like cache reduction (22x) or in some
particular cases like using a little of the repository downloaded
which brings to a disk usage reduced by 11x times. About building
time, the ratios are a little under-estimated because network
downloads for debootstrap and apt update take a fixed time that cannot
be reduced. My first tests indicate that also custom debian packages
and repackaged .deb are correctly deployed into the system despite the
changes. More tests are welcome.

 Best regards, R-
