Sandbox

Requirements

• cgroup v2

  To use cgroup v2, you might need to change the configuration of the host init system. Fedora (>= 31) uses cgroup v2 by default and no extra configuration is required. On other systemd-based distros, cgroup v2 can be enabled by adding systemd.unified_cgroup_hierarchy=1 to the kernel cmdline.

• gcc-10

• libcgroup, libecap

Common issues

• memory.swap.max group parameter does not exist

  Swap accounting can be enabled by adding systemd.unified_cgroup_hierarchy=1 to the kernel cmdline.

• freezer subsystem is not mounted

  $ mkdir cgroup-freezer
  $ sudo mount -t cgroup -ofreezer none cgroup-freezer/
