encrypted swap reused from previous install when wiping and reinstalling

[Paul Larson]

I've been able to reproduce this easily on both amd64 and panda, so it does not appear to depend on arch.

1. install raring with lvm+crypt selected
2. once that install is complete, reinstall using the same drive/system, this time select to have it "Erase Ubuntu and reinstall"
3. once the install is complete, reboot to the newly installed system and run 'cat /proc/swaps'

It would be expected to see /dev/sda? here due to automatic creation of a swap partition at install time. However after installing with lvm+crypt, it seems to reuse the old encrypted volume from the previous install (/dev/dm-0).

Needs checking if this can also be reproduced with ubuntu server cd.

[Paul Larson (pwlars)]

Using the server cd, I did the equivalent process: Install with lvm+crypt, then reinstall using guided partitioning/use full disk. When doing this, it did not reuse the previous swap partition. Contents of /proc/swaps after the 2nd install indicated /dev/sda5 was being used instead of /dev/dm-?

[Dimitri John Ledkov (xnox)]

By default in partman we do specify to reuse the swap partition if one exists on the system already.
The fact that server cd != desktop cd case is a little surprising to me, unless there are further ubiquity specific delta there.
