But then, you have to anyway tweak lttng to pass:

LTTNG_LIBUST_CONF_OPTS += --with-lttng-system-rundir=/run/lttng

but unconditionally, and no longer depending on whether systemd is used
or not. Correct ?

But... /run is already a tmpfs in sysv-based systems, so what prevents
today from using /run/lttng even for sysv based systems ?
