  After upgrading a server from 10.04 to 12.04 I saw errors on boot about udev trying to use a non-existent vol_id:
  failed to execute '/lib/udev/vol_id' 'vol_id --export /dev/md0': No such file or directory
  
  I tracked this down to the following line in /etc/udev/rules.d/65-mdadm.vol_id.rules:
  IMPORT{program}="vol_id --export $tempnode"
  
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=541884 mentions this issue and says that we should be using '/sbin/blkid -o udev -p ...' instead. Indeed, checking /lib/udev/rules.d/64-md-raid.rules, it has:
  IMPORT{program}="/sbin/blkid -o udev -p $tempnode"
  
  I then updated /etc/udev/rules.d/65-mdadm.vol_id.rules to use this
  instead, and the errors went away.
