Bug#678015: debian-installer: Guided partitioning took 26 hours to complete erasure of encripted LVM volume
I've recently tried the weekly built netinst image of Debian Installer to install Wheezy on
a computer with a hard disk of 640 GB.
I wanted to experiment with encripted volumes, so to get an idea of what could be a sensible
setup, I tried the guided partitioning option for encripted LVM. I just wanted to see what
was Debian's recipe for that setup before coming up with my own.
Unfortunately, the installer decided to erase (very thoroughly I learned too late) all data on
the newly created 632 GB volume it, which took roughly 26 hours.
Had I been asked, I would have chosen no to wipe out the volume, because no sensitive
information was previously there, just the proprietary pre-installed operating system that
I never intended to use, but came with the computer anyway.
Besides, even for sensitive information, a 26 hour-long erasing on an average hardware, with
no prior notice or confirmation is IMHO not what the installer should do.
a) changing the erase algorithm for someting more expeditive, even at the expense of some
b) asking the user if she actually wants to erase the contents of the newly created volume;
c) warning the user that the erasing could take more than 1 day.
