Bug 1090483

+++ This bug was initially created as a clone of Bug #958179 +++

Description of problem:
Sosreport currently collects a limited set of files from /proc and /sys. This includes sysctl pseudofiles, module parameters and files relating to certain device types in sysfs.
 
Additional data would be useful to support the analysis of customer problems.
 
The following specific areas of /sys should be included in the report at a minimum. Some are in SOS but most of them are missing. Ideally we would like to gather all of it if possible. See script below.

/sys/block/*
/sys/class/*
/sys/module

/proc/sys/*


Version-Release number of selected component (if applicable):
sos-2.2-*

How reproducible:
100%

Steps to Reproduce:
1. sosreport --batch
2. tar xf <sosreport archive>
3. Inspect sosreport_path/sys/... 
  
Actual results:
Required file entries in /sys and /proc are not present

Expected results:
Need them included

Additional info:

The following script is a script we currently use to achieve the same manually outside of sosreport.
