No, the programmer does not mount anything. Programmer writes
application which wants to create a subgroup. System admin is the one
who decides what is mounted how. And the programmer (=me) needs a way
how to reliably create a subgroup, without knowing details about all
controllers. E.g. 'blkio' controller is quite new one, old applications
do now know anything about it, yet according to your idea, the
application *must* provide sane defaults to it.
