All flavours of Ubuntu use a locked root and force all users to systematically use sudo; the su command won't go anywhere because there is no root password. (It is possible, though strongly discouraged, to unlock and later relock the root account, as explained here: https://help.ubuntu.com/community/RootSudo) The short and sweet of it is that (nearly) all super-user operations under Ubuntu will be conducted by a user (with sudo privileges), not by the root account. Hence the shenanigans I ran into. It sounds like LTTng will have to adjust the way it allocates the root .lttngrc path under Ubuntu systems, so that it uses /root/.lttngrc instead of ~/.lttngrc Daniel U.
