Title:
  Ureadahead on btrfs slows down boot

Status in “ureadahead” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: ureadahead

  I am running 10.10 beta on btrfs root, but had some boot performance
  isues, found out that ureadahead is slowing down my boot significantly
  (about 5 secconds on the chrono)

  there are two ways to handle this issue:
   - make ureadahead detect that it's on a btrfs and do nothing (the easy lazy way)
   - make ureadahead btrfs compatible (it should be even posible to make use of the btrfs online-defrag feature to improve performance even more)
