** Description changed:

- When I try to install Ubuntu Precise Pangolin using LVM for my
- filesystems, it gives me this warning:
+ When I try to install Ubuntu Precise Pangolin with my filesystems on LVM

-   Could not stat device /dev/mapper/hostname-root - No such file or
+   Could not stat device /dev/mapper/hostname-root - No such file or

  If I select "Retry", everything works.
  
  It appears that the LVs are created, but their entries in "/dev/mapper"
  don't exist yet when the rest of the system tries to use them.

Bug description:
  When I try to install Ubuntu Precise Pangolin with my filesystems on
  LVM volumes, it gives me this warning:

    Could not stat device /dev/mapper/hostname-root - No such file or
  directory.

  If I select "Retry", everything works.

  It appears that the LVs are created, but their entries in
  "/dev/mapper" don't exist yet when the rest of the system tries to use
  them.

  After I retry, the entries do exist and so everything works.

  An easy fix seems to be adding a short delay after creating the LVs,
  so they are ready by the time other parts of the install process
  begin.
