  should copy /etc/udev/ rule if available

  Fix Released

Bug description:
  [IMPACT]

   * Previously overriding the system mdadm rule was not copied into
  initramfs, thus had no effect at boot

   * The fix is to check for existence of the mdadm rule override in the
  /etc/udev/rules.d and copy it into the initramfs in addition to the
  system udev rule

  [TESTCASE]

  * Touch the udev rule overrided (Note old package ships two udev rules as per bug 1002357):
  * Update the initramfs
  * Unpack the initramfs NB! use your correct name for the inird.img file name!
  * Search for the udev rule override

  $ sudo touch /etc/udev/rules.d/65-mdadm-blkid.rules
  $ sudo touch /etc/udev/rules.d/85-mdadm.rules
  $ update-initramfs -u
  $ cd `mktemp -d` && gzip -dc /boot/initrd.img-3.4.0-5-generic | cpio -ivd
  $ find -name '*.rules' -empty
  # No output

  * Upgrade the package and repeat

  $ sudo touch /etc/udev/rules.d/64-md-raid.rules
  $ update-initramfs -u
  $ cd `mktemp -d` && gzip -dc /boot/initrd.img-3.4.0-5-generic | cpio -ivd
  $ find -name '*.rules' -empty
  # Expect the location of the empty rules override

  
  [Regression Potential] 

   * Systems administrators who by lucky chance where overriding upsteam
  udev rules name, which previously was not present on Ubuntu, may be
  surprised or annoyed that their change now got copied into initramfs
  and affected their boot.

   * Same as in the bug 968074, the default udev rule has changed. Users
  who relied on the previous, incomplete/broken, udev rules may be
  pleasantly surprised or annoyed that the udev rule name has changed to
  match the one of Debian and upstream.

   * System administrators need to check their /etc/udev/rules.d/ to
  make sure that (a) they do not override mdadm rules (b) if they do,
  check that those overrides are still needed (c) that the override is
  named to match the new udev rule name.
