Title:
  invalid udev rules shipped in mdadm-udeb

Status in mdadm package in Ubuntu:
  Fix Released
Status in mdadm source package in Bionic:
  Fix Released
Status in mdadm source package in Cosmic:
  Fix Released

Bug description:
  [Impact]

   * Upon installation, RAID devices are not automatically assembled by
  default as they used to be. Instead of being presented with an
  assembled RAID array for installation, one is presented with
  individual disks which probably is not desired by the user, as most of
  the time RAID arrays are intentional.

  [Test Case]

   * Create a VM with e.g. two disks assembled in a Linux RAID1 using
  mdadm and not otherwise partitioned / empty.

   * Start the d-i based installer

   * In the partitioning screen one should be presented with a raid
  device to partition, not individual disks.

  [Regression Potential]

   * This is a regression in the bionic release versus Xenial behaviour

   * The udev rules as installed into the udeb package were not
  processed to substitute template variables for BINDIR location of the
  mdadm tools. Now the packaging was corrected to install identical udev
  rules into the deb and udeb package types.

  [Other Info]
   
   * Original bug report:

  It is not possible to install Ubuntu on RAID device with IMSM/DDF
  metadata. The installer asks if such arrays should be activated but
  fails to do it.
