Enable KSM (Kernel Same-Page Merging) on boot in Debian

I have installed and run Netdata on my Debian based home server and I wanted to enable KSM after Netdata installer suggested it could save some RAM.

To enable the KSM on boot in Debian you I executed these steps:

  1. Install ksmtuned without all the QEMU dependencies:
sudo apt-get install ksmtuned --no-install-recommends
  1. I actually don't need the ksmtuned.service and I did disabled it:
sudo systemctl stop ksmtuned.service
sudo systemctl disable ksmtuned.service
  1. Finally if:
sudo cat /sys/kernel/mm/ksm/run

returns 0 restart the ksm.service:

sudo systemctl restart ksm.service

Has it been enabled in the kernel that you are running?
