Question 6 of 10

Read the output

labmember was added to lab-writers. Why does his `sleep` process not have that group?

$ id -nG labmember
labmember lab-readers lab-writers
$ ps -o pid,supgrp,comm -u labmember
    PID SUPGRP                 COMMAND
   1404 lab-readers,labmember  sleep

ps does not show groups added after the machine booted.
The process got its groups when it started, before lab-writers was added.
Changing the account damaged the process.
Processes get the lab-writers group from the next boot of the machine.
