Hello, I would like to suggest a new option in the Debian GUI installer. Currently, when you enable full disk encryption with LUKS, it automatically overwrites all the bits in the drive in the secure delete step before enabling LUKS and installing Debian.
Although this is more secure because it erases all remaining data on the drive and makes it harder to guess where the new encrypted data is and where the old data is, there are some users who want to skip this step in order to cause less damage to the drive, or because their drive already had random or encrypted values. It would be nice to have a checkbox that allows you to select whether or not to perform the secure delete after you have chosen to encrypt the disk in the GUI installer.
