Quiz: limits and kernel parameters

Question 6 of 10

One correct answer

After `sudo sysctl -w vm.swappiness=10` and a reboot the parameter is 60 again. What do you do so that 10 survives a reboot?

Put echo 10 > /proc/sys/vm/swappiness into ~/.bashrc.
Write vm.swappiness = 10 to the /etc/sysctl.d/swap.txt file.
Write vm.swappiness = 10 to an /etc/sysctl.d/<number>-<name>.conf file and apply it with sudo sysctl --system.
