Bug#432088: pbuilder: please use APTCACHE on --create

[Ritesh Raj Sarraf]

Package: pbuilder
Version: 0.226.1
Followup-For: Bug #432088

Hello Mattia,

Is there any way to solve this bug ?

On --create, it really is annoying. Because even a single deb failure
will result in the whole thing to be downloaded again.

Ideally, APTCACHE should be used. But looking at the code, it seems the
download is done by debootstrap, which does not seem to have that
intelligence.

Please reassign if you think/agree that this is beyond pbuilder's scope
and should be assigned to debootstrap.
