Faster installation when choice of encrypting disk

The default behavior of debian installer used in Helium and Lithium, with choice of encrypting disk, is to wipe entire disk, before formating and installing.
Overwriting entire disk with zeroes, takes considerable time.

If you are installing your own system, there is probaley no need to wipe out previous information.
It is not possible to opt out wipe.

A workaround is to just abort wipe when it starts.

Continue installation, accept chosen partition cheme and continue with formating.

You will have saved a lot of time.

Re: Faster installation when choice of encrypting disk

^Maybe add a note that this only applies when encrypting the disk?

The other installer choices (Guided, LVM, Manual) do not enforce data erasing.

Yes but no encryption options offered with that choice (Guided formatting).

I guess few people use encryption, more people using laptop with sensitive data or "confidentiality paranoia" (like me LOL)

I don't think it's a big thing/issue " but" if some note somewhere for people choosing to encrypt was possible, it could save 30 minutes to 1 hour or more to some people trying the distro with encryption...  The most patient will search in the forum and see the solution...

Re: Faster installation when choice of encrypting disk

^Thanks. I'm pretty sure this is a change in the behaviour of Debian Installer in the last release or two. In the past I remember when choosing to encrypt, being asked whether I wanted to erase the data first or not. I guess the developers decided it was a Good Thing to do that by default. The installer does say something about "encryption quality" at that point.
