mdadm (3.3.2-5) unstable; urgency=medium
* use-tempnode-not-devnode.patch: change udev rules file to use $tempnode which works both on wheezy and jessie udev, instead of $devnode which only works in jessie. At this stage it is better to make rules file compatible with old version instead of adding versioned dependency. Should be removed for jessie+1. (Closes: #770883) * fix Closes: list in previous entry (Closes: #771852) # imported from the archive
