| # -p: enter new pid namespace (implies -vr). |
| # -u: change userid to <user> |

| # -G: inherit supplementary groups from new uid. |
| # -c: grant capabilities for lvm2 utils to access dm devices and create |
| # lock files. |
| # -n: set no new privileges (no_new_privs bit). |
| # --seccomp-bpf-binary: use the spaced seccomp policy |
