Extract the kernel checking code from /usr/lib/python2.7/site-packages/tracer/resources/tracer.py and run it on the machine :
------
def _has_updated_kernel(self):
if os.path.isdir('/lib/modules/'):
for k_version in next(os.walk('/lib/modules/'))[1]:
if parse_version(os.uname()[2]) < parse_version(k_version):
return True
return False
return False
-----
Run it on the machine after modifying it to print the valuses:
-----
import os
from pkg_resources import parse_version
print "All Installed Kernel"
print next(os.walk('/lib/modules/'))[1]
print "Current running kernel"
print os.uname()[2]
for k_version in next(os.walk('/lib/modules/'))[1]:
if parse_version(os.uname()[2]) < parse_version(k_version):
print parse_version(os.uname()[2])
print parse_version(k_version)
-----
The output:
All Installed Kernel

Description of problem: - If the kernel-debug is installed on the machine, the tracer command output will be like the following even after rebooting the machine. You should restart: * These applications rebooting your computer: kernel - This will case the machine to be marked as "Reboot Required" on the machine Properties and on Content Hosts Application | Type | Helper kernel | static | You will have to reboot your computer Version-Release number of selected component (if applicable): katello-host-tools-tracer-3.3.5-3.el7sat.noarch tracer-common-0.7.0-3.el7sat.noarch python2-tracer-0.7.0-3.el7sat.noarch How reproducible:Confirmed Steps to Reproduce: 1. Install katello-host-tools-tracer package on any registered machine. 2. Install kernel-debug package 3. Reboot the machine. 4. Run "tracer -a" 5. Check the machine on the satellite "All Hosts" and "Content Hosts -> Traces" Actual results: You should restart: * These applications rebooting your computer: kernel Expected results: The machine does not need to be rebooted because of the kernel.
