I have seen evidence to suggest that on Ubuntu 20.04 you add this line to /boot/firmware/cmdline.txt per Enabling memory cgroup in Ubuntu 20.04, however I have a /boot directory but not /boot/firmware, so where should I specify this for Ubuntu 21.10 ?

I found a solution to this here: How to run cgexec without sudo as current user on Ubuntu 22.04 with cgroups v2, failing with "cgroup change of group failed"?

I tested this on a x86_64 device running Ubuntu 22.04.:

sudo nano /etc/default/grub

Edit this line like so:


GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1 systemd.unified_cgroup_hierarchy=false"


sudo update-grub
sudo reboot

A note to anyone enabling cgroups for AWS Greengrass: Edit GRUB_CMDLINE_LINUX to be:

GRUB_CMDLINE_LINUX="cgroup_enable=memory cgroup_memory=1 systemd.unified_cgroup_hierarchy=0"
