Title:
  ureadahead doesn't wait for /sys/kernel/debug

Status in “ureadahead” package in Ubuntu:
  Expired

Bug description:
  Hello,

  I'm trying to improve my boot time, and in order to do that I need to
  get ureadahead reprofiling because currently it isn't doing too good
  of a job. So I deleted my pack files, but I get

  init: ureadahead main process (372) terminated with status 5

  In the system logs. If tracked this down to a problem of debugfs not
  being mounted at the time that ureadahead is run. If I alter so we
  have:

  start on mounted MOUNTPOINT=/sys/kernel/debug TYPE=debugfs

  In the ureadahead.conf file in etc/init, profiling starts working
  again.

  There's a slow down if you leave that for when ureadahead does the
  readahead and not the profiling, so I don't know how to fix this
  problem. One solution is to have two separate processes, maybe add an
  option to readahead like --profile to explicitly profile, and then
  have two process on bootup. One that reads ahead and one that profiles
  after the read process is done, kind of like what Scott said in
  #482767
