partitioning


        ifconfig em0 slice ssh bandwidth 100M
        ifconfig em0 slice http bandwidth 100M
        ifconfig em0 slice https bandwidth 500M
        ifconfig em0 slice smtp bandwidth 100M
        ifconfig em0 slice dns bandwidth 100M
        ifconfig em0 slice ntp bandwidth 50M
        ifconfig em0 slice snmp bandwidth 50M

wait. I don't have to do that. it's dynamic.

but I have to split disk space in advance. why?
