As in the lttng manual [1]:
Most distributions mark the LTTng-modules and LTTng-UST packages as
optional when installing LTTng-tools (which is always required). In
the following sections, we always provide the steps to install all
three, but note that:
* You only need to install LTTng-modules if you intend to use the
Linux kernel LTTng tracer.
* You only need to install LTTng-UST if you intend to use the user
space LTTng tracer.
there should be no force dependency between lttng-tools and
lttng-modules. When set lttng-modules in RRECOMMENDS, it always
forces
to build lttng-modules whether it is required or not.
Compare to rpm spec [2] and debian conf [3], there are no any
dependency
between them too.
So remove the RRECOMMENDS setting.

The removal of the dependency probably makes sense but we need to add
lttng-modules to packagegroup-core-tools-profile instead.
OK. v2 will be sent.
Thanks,
Kai
