I am running Centos 6, I wish to tweak something under /sys on boot, what is the
best way of doing it ?

If I want to initialise something under /proc I can put it into /etc/sysctl.conf
--- is there something equivalent for /sys ?

OK: I can always write my own init script, but ....

What I want to achieve is:

    echo 1 > /sys/devices/system/cpu/sched_smt_power_savings

which will:

    One core will be filled with tasks before tasks will be moved to other
    cores. The idea is to concentrate the running tasks on a relatively small
    number of cores, allowing the others to remain idle.
