This change will hopefully trickle down to older release and wi= ll avoid the SElinux / AppArmor issues in the default case (which led t= o downstream Ubuntu and Fedora disabling LTTng-UST support). Anyone th= at wants to use LTTng-UST (i.e. for generating RBD replay traces) can e= nable the support and adjust their SElinux / AppArmor rules to accommod= ate.
