Comment 23 for bug 432089

This has been uploaded to karmic-proposed, since the kernel patch is there (though that might take some more cooking due to other patches in the kernel upload):

Changes:
 ureadahead (0.90.3-2) karmic-proposed; urgency=low
 .
   * über-readahead is a replacement for sreadahead that should
     significantly improve boot performance on rotational hard drives,
     especially those that had regressed in performance from jaunty to
     karmic.
 .
     It does this by pre-loading such things as ext2/3/4 inodes and opening
     files in as logical order as possible before loading all blocks in one
     pass across the disk.
 .
     On SSD, this behaves much as sreadahead used to, replacing that package
     with slightly improved tracing code.
 .
     This requires the kernel package also found in karmic-proposed.
 .
     LP: #432089.
