Bug#611196: debian-installer: Make "Erasing data" step optional

[Pavel Zubkou <pavel.zubkou@gmail.com>]

Package: debian-installer
Severity: wishlist

Using Squeeze installer RC2 (text mode via "Install" option from boot menu), after selecting "Guided, entire disk, encrypted LVM" as a partitioning mode and confirming it, there is a long process of erasing data from partition #5.

As I am installing Debian on a new system with a blank disk it will be prefered to omit "Erasing data" step by telling installer not to do it, because it is time-consuming and obviously not needed on a new disk.
