>AFAICT our kernel config is set to performance - why not just set it to
ondemand?

So from my understanding, the point of the ondemand script is really so
we can have boot set to performance, and then switch later to something
that saves more power.  The goal is boot performance so If we survey
machines and find that's it's harming or negligible to boot performance
that makes a compelling argument against it - correct?

Title:
  Drop ondemand init script

Status in sysvinit package in Ubuntu:
  Confirmed

Bug description:
  Ondemand init script is not inherited from Debian, it's an Ubuntu
  specific change.

  Some reasons to get rid of it:
  On my wily cloud test, systemd blame's 669ms on ondemand on a cloud instance with no ability to change frequency..
  In the init script we don't run this for android 
  Ondemand is already on by default!  Why don't we just always use whatever is that kernel's default?

  There are a number of other reported problems with it:
