I have an open PR [1] to dynamically enable LTTng-UST via new config options. This change will hopefully trickle down to older release and will avoid the SElinux / AppArmor issues in the default case (which led to downstream Ubuntu and Fedora disabling LTTng-UST support). Anyone that wants to use LTTng-UST (i.e. for generating RBD replay traces) can enable the support and adjust their SElinux / AppArmor rules to accommodate.
