Unclear Which Claude Code feature sets a cgroup for commands is not known, so it is unclear when this applies.
What
Linux can group programs together to limit how much memory or processor time they use. These groups are called cgroups, and they come in an older layout (v1) and a newer one (v2).
When Claude Code starts a command with a cgroup set, and the system does not report the v2 layout, it now runs the command through a small shell step. That step first adds the command to the group and then runs it. In every other case, the command starts directly as before.
Why
This makes resource limits work on Linux machines that still use the older cgroup v1 layout.
