[Bug 1066480] Re: Installer doesn't show encrypted partitions

[Dmitrijs Ledkovs]

partman-crypto does support activating existing volumes on ubuntu.
In d-i interface, one needs to enter manual partitioning, enter encryption sub-menu and select option to activate existing encrypted volumes. At which point all encrypted volumes will be attempted to be activated and user maybe asked for a password (multiple times, if there is more than one encrypted volume). After which one needs to back-out to automatic partitioning & gain options to for example upgrade encrypted volume.

This "loop via activating crypt volumes" can be implemented directly, or
we can modify ubiquity's embedded d-i to execute that option for us and
do question pop-ups about that.

But there is a caveat, once activated one cannot "deactivate" those
volumes. See bug 291494 .

Also "resize" option can be dangerous, as there is no proper resize
support for neither LVM2 nor dm-crypt volumes.

The "upgrade" or "reuse" options can be dangerous as well, since I am
suspecting that lvm2 and/or ecryptfs user space tools might not be
installed. In any case those options should be tested.

Bug description:
  Hallo
  Testing 20121014 amd64 desktop in virtual env.
  in the disk was already present an encrypted Ubuntu installation, and when I try to install a second Ubuntu it don't consider the encrypted partitions, suggesting to erase all the disk instead to instal along side.
  But I want a free system for my son and an ecrypted one for my work on the same disk.
  Attached screenshot
  Thanks
  Fabio

  We can also see that the partition is regularry mounted and showed in
  launcher.
