I'm missing some pieces of the puzzle: is this a problem of permissions
? (I'm seeing the sysdefault/tasks file has rw- for others, whilst the
root group tasks file has r-x !?!). What is the scenario where you run
into this problem ?

thanks, this is the easy'n'quick fix for me, as of now.
I guess in my case I could also add to cgconfig.conf
group sysdefault {
cpu.rt_period_us = ...
cpu.rt_runtime_us = ...
...
}
Right ? Is the default group created before proceeding to execute the
cgconfig `group' commands ?
