To enable cgroups accounting, you must boot Linux with the command line parameters @cgroup_enable=memory swapaccount=1@.
+Currently Arvados is not compatible with the new cgroups accounting, also known as cgroups v2. Currently, all supported GNU/Linux distributions don't use cgroups v2 as default
+If you are using a distribution in the compute nodes that ships with cgroups v2 enabled, make sure to disable it by booting Linux with the command line parameters @systemd.unified_cgroup_hierarchy=0@.
