** Description changed:

- Binary package hint: debian-installer
+ [IMPACT]
  
- I have a ubuntu 7.10 beta server I'd like to reinstall from scratch.
- During the disk partitioning, I'd opted for "Guided - Use entire disk
- and setup LVM" Part way through it informed me that the volume group
- name was already in use. Surely this option should setup a new LVM
- instance and use the entire disk, even if a LVM instance already
- existed?
+  * Fail to pre-seed automatic LVM installation on machines with:
+ - empty / new partition table
+ - not-zeroed out disks
+ - which had the same partition layout
+ - and the same volume group names
  
- How can I blank this without manually having to create volumes? I think
- this is a bug
+  * this affects large scale automated installs / deployments, as it is
+ very easy to get all of those conditions when reinstalling.
+ 
+  * To fix this bug partman-auto-lvm should be updated with the proposed fix
+  * the fixed partman-auto-lvm should also make it onto affected images
+ 
+ [TESTCASE]
+ 
+  * Pre-seed or manually execute "Guided partitioning - LVM"
+  * Remove/Clear partition table with e.g.:
+ 
+ # fdisk /dev/vda << EOF
+ o
+ w
+ EOF
+  
+  * Pre-seed or manually execute "Guided partitioning - LVM" again
+ 
+ [Regression Potential]
+ 
+  * while the current behaviour is broken, it did allow to "resurrect"
+ LVM groups by bailing out the install after the zombie VGs groups became
+ detected, but it is not guaranteed that the resurrected VGs are correct:
+ the partition can be too small and VG can be incomplete (only 1 out of
+ many physical volumes). Some people may have been relying on this. The
+ correct behaviour will attempt to delete the zombie VGs by asking a
+ question that can be pre-seeded or manually backed out of.
