On the topic of FS compression(also FS caching and delayed allocation).

The real issue I had was the calculation of install size when building
the package. The calculated size was always *very* small. I addressed
this issue with 2 patches. The 1st one (adding sync before running du)
didn't fix anything. The 2nd patch worked pretty well.
