Do you know difference between "start" and "restart"?

i guess restart means it is restarted by runsv.

e.g.

[root@ve11a:Active:In Sync] config  tmsh show sys service snmpd
snmpd        run (pid 22409) 7 days, 1 start

[root@ve11a:Active:In Sync] config  tmsh restart sys service snmpd
[root@ve11a:Active:In Sync] config  tmsh show sys service snmpd
snmpd        run (pid 8075) 3 seconds, 2 starts

[root@ve11a:Active:In Sync] config  ps -elf | grep /usr/sbin/snmpd | grep -v grep
4 S root      8075  5951  3  80   0 -  9918 -      23:04 ?          0:00 /usr/sbin/snmpd -f -c /config/snmp/snmpd.conf -I-ifTable ifXTable ipAddressTable -Lsd -LF 6 /var/log/snmpd.log -p /var/run/snmpd.pid

[root@ve11a:Active:In Sync] config  kill -9 8075

[root@ve11a:Active:In Sync] config  tmsh show sys service snmpd
snmpd        run (pid 8213) 5 seconds, 2 starts, 2 restarts
