Avoid root logger setup when SELinux helper is missing - #30
Merged
Conversation
When testcloud's has_selinux() runs on systems where the selinuxenabled
command is not installed. The FileNotFoundError handler used
module-level logging.debug(), which implicitly calls
logging.basicConfig() when the root logger has no handlers.
That creates a default root StreamHandler. Libraries such as tmt use
propagating DEBUG-level loggers with their own filtering, so once the
root handler exists, their records also get emitted with Python's
default format which clutters CI output e.g. [1],

Log through the testcloud.util module logger instead, preserving the
existing library-mode NullHandler behavior and avoiding implicit root
logger configuration. Add a regression test for the missing
selinuxenabled path.
