Dear bests

I would like to know if you think that taskset tool can help me about my
needs :

http://linux.die.net/man/1/taskset

Do you think that doing

taskset -c 1 postmulti -i postfix-[instance] -p start

will do the trick

I'm afraid that only postmulti will set to processor 1 but will not send it's cpu settings to master

best regards
