readahead-fedora 2:1.5.6-5.2 (ppc64el binary) in ubuntu vivid

 "readahead" is the term used to refer to a tool that preloads files in
 this case used during the boot process to make the system boot faster.
 .
 This implementation of the tool provides the following features:
  * It can take multiple lists of files to be preloaded, and sort them
    according to their position on the disk.
  * It preloads the inode tables on ext2-based file systems.
  * It opens the files without making the system update their access
    time, therefore avoiding extra disk writes.
  * It uses a lightweight monitoring daemon.
