** Description changed:

+ Impact: dmraid installation is entirely broken in Lucid.
+ 
+ Development branch: For the time being, an upstream patch has been
+ reverted in Maverick: see comment 84 and http://bazaar.launchpad.net
+ /~ubuntu-
+ branches/ubuntu/maverick/parted/maverick/annotate/head:/debian/patches
+ /fix-dmraid-regression.patch; however, in future (probably in maverick)
+ we'll fix this differently by switching to the new naming scheme for
+ device-mapper devices, which has more consistent support in upstream
+ code.  Such an invasive change would not be appropriate in Lucid - for
+ one, it would require changes to grub2.
+ 
+ Patch: https://code.launchpad.net/+branch/ubuntu/lucid/parted
+ 
+ TEST CASE: Install Ubuntu on a DM-RAID system using (a) the Ubuntu
+ desktop CD and (b) the Ubuntu server CD.  Verify that it succeeds.  Note
+ that this requires respins of CD images to test effectively; Colin
+ Watson will arrange for sample daily builds not long after this update
+ is processed.
+ 
+ Regression potential: This change is isolated to code dealing with
+ device-mapper devices, so installations on ordinary hard disks should be
+ unaffected.  However, I think it would be a good idea to regression-test
+ installations on LVM and software RAID (as distinct from DM-RAID), as
+ those follow the same code path and may be affected.
+ 
+ Original report follows:

  Binary package hint: dmraid
  
  Fresh install of Ubuntu Server 10.04 Beta 2 using Sil 3124 fakeraid
  controller card.  Ubuntu install successfully detects fakeraid set
  (Raid1) and activates it, but after creating my partition layout using
  all default options with "Guided Partitioning",when I click finish to
  apply it, it fails stating it could not create a filesystem.
