Could you switch the cobblerd_t domain to permissive, re-run your scenario and collect SELinux denials? # semanage permissive -a cobblerd_t (re-run your scenario) # ausearch -m avc -m user_avc -m selinux_err -m user_selinux_err -i -ts recent Thank you. # ausearch -m avc -m user_avc -m selinux_err -m user_selinux_err -i -ts recent
