The problem description in .pdf format - easy to follow

Hi,
  First I want to notice I am a Linux newbie and my English is not that good.

  Now straight to the point! (The same description is available in the attached
pdf file and is more easy to follow)

  I've noticed some inaccuracy in Fedora 17 “Power Management Guide” (Fedora
Documentation), particularly in section “2.5. Tuned and ktune” including
“2.5.1. The tuned.conf file” and “2.5.2 Tuned-adm”.

  In section “2.5. Tuned and ktune” right bellow the “yum install tuned”
command it's written:

“Installing the tuned package also sets up a sample configuration file at
/etc/tuned.conf and activates the default profile.” 
There is no such file in /etc. I found a /etc/tuned/active_profile file
containing the following: “/usr/lib/tuned/balanced/tuned.conf”. I'm not sure
this file (/etc/tuned.conf) is missing only on my system or it has a new
location by default for each profile - /usr/lib/tuned/profileX/tuned.conf.
Bellow in this section and in  “2.5.1. The tuned.conf file” it is pointed again
that the default location for the tuned.conf file is /etc/tuned.conf.

In section “2.5.2 Tuned-adm” in the first paragraph it is written “Fedora 17
includes a number of predefined profiles for typical use cases...”. Just to be
precise it is good to be mentioned that these profiles are not installed by
default with “yum install tuned” command (tuned-2.0.1-1.fc17 package), but can
be found in tuned-profile-compat-2.0.1-1.fc17 package (I found it in Gnome
Package Manager). 
Another thing in this section is in the last third of the page where it is
written:
“All the profiles are stored in separate subdirectories under
/etc/tune-profiles. So /etc/tune-profiles/desktop-powersave contains all the
necessary files and settings for that profile. Each of these directories
contains up to four files:”
There /etc/tune-profiles directory does not exist. Instead I found the profiles
stored in /run/lib/tuned.
Each directory for the corresponding profile typically contains only 2 files -
script.sh and tuned.conf. The presence of script.sh is not mentioned in the
directories contains description – it is mentioned ktune.sh insetad.  


That's all. I hope this is helpful.

Best regards

Vasil Draganov

Fedora 17   3.4.0-1.fc17.x86_64

P.S. “Power Management Guide” is great. It's really useful. The moment i run
tuned service i noticed how quieter my laptop became (less heat – less fan
needed :) ). The first thing I noticed about new Fedora installation was that
the laptop was noisier in comparison to Win7 (I dual-boot with Win7). Tuned
just fixed that :)
Many thanks to the creators of Fedora Documentation!!!
