Run a program with some namespaces unshared from the parent.
-m, --mount[=<file>] unshare mounts namespace
-u, --uts[=<file>] unshare UTS namespace (hostname etc)
-i, --ipc[=<file>] unshare System V IPC namespace
-n, --net[=<file>] unshare network namespace

-U, --user[=<file>] unshare user namespace
-C, --cgroup[=<file>] unshare cgroup namespace
-f, --fork fork before launching <program>
--mount-proc[=<dir>] mount proc filesystem first (implies --mount)
-r, --map-root-user map current user to root (implies --user)
--propagation slave|shared|private|unchanged
modify mount propagation in mount namespace
-s, --setgroups allow|deny control the setgroups syscall in user namespaces
-h, --help display this help and exit
