Hi all,
Thanks to Uladzimir who pointed me out about the weirdness of ln -P in sbuild
and other changes that I made, nvpriv7 is clearly faster than npriv6. Here
below the benchmarks compared with the original based on robang74:next.

About the complete image, we need to consider some fixed times like these:
* time to produce complete wic image: 2m23s
* time to compile nvidia drivers: 2m8s
Because these times cannot be shrink as part of the building process then we can
subtract that times (for the cache just producing the image because the drivers
are cached) and revise the benchmarks as following:
fresh cache
------------ complete --------------
time: 8m14s | time: 1m48s 4.57x
------------ original ---------------------
time: 16m46s | time: 6m05s 2.76x
2.03x | 3.38x
Even in the worst case, the building performances has been increased by 2x
