Hi,
Thank you for help on SELinux policy for zoneminder!
Could you send me please raw AVC messages (SELinux denials) from audit log?
Please, reproduce your scenario how you're using zoneminder policy and
then attach output of:
# ausearch -m AVC -ts today -m USER_AVC
I would like to also see these messages, before I merge it with Fedora
distribution policy.
Thanks,
Lukas.
