- Sometimes the run_command caller doesn't want to have a failure
logged as error, since such failure can be expected. This patch adds
an option in run_command to log errors in debug mode to avoid give
false positives to users.
Jose Ricardo Ziviani (2):
Add option 'silent' in run_command
Change getsebool to run silently.

New subject: [PATCH 1/2] Add option 'silent' in run_command
- With this new option the caller can choose if run_command errors will
be logged as error or debug. There are cases where a command error is
expected and don't need to alert users.

New subject: [PATCH 2/2] Change getsebool to run silently.
- getsebool virt_use_sysfs exists in RHEL6 and older distributions
only. Newer distros don't have it but run_command alerts there is an
error in Kimchi. This is not an error but a expected behavior. For
this reason, this command now will only log for debugging purposes.
