If you use functional and share-tree policy concurrently the effect of
both are combined with the relation

   weight_tickets_functional : weight_tickets_share

as configured in sched_conf(5). E.g. if you've configured a 2:1 relation
and use similar share distribution with your functional and share-tree
set-up your users/projects would be slightly penalized. If it is 1:2
users/projects would be stronger penalized.

Note however that share-tree policy itself provides own means to
align the degree of penalization (compensation_factor).
