nsenter: passing command arguments

[Nicolas <nicolas.delaby@ezeep.com>]

Hi,
I'm struggling with nsenter to call commands with options because they 
are caught by nsenter and complain this is an invalid option.

How can I pass any arbitrary argument ?

Thanks for reading,
Nicolas

```
$ nsenter --target $PID --mount --uts --ipc --net --pid ls -a
nsenter: invalid option -- 'a'

Usage:
  nsenter [options] <program> [args...]

Options:
  -t, --target <pid>     target process to get namespaces from
  -m, --mount [=<file>]  enter mount namespace
  -u, --uts   [=<file>]  enter UTS namespace (hostname etc)
  -i, --ipc   [=<file>]  enter System V IPC namespace
  -n, --net   [=<file>]  enter network namespace
  -p, --pid   [=<file>]  enter pid namespace
  -U, --user  [=<file>]  enter user namespace
  -S, --setuid <uid>     set uid in user namespace
  -G, --setgid <gid>     set gid in user namespace
  -r, --root  [=<dir>]   set the root directory
  -w, --wd    [=<dir>]   set the working directory
  -F, --no-fork          do not fork before exec'ing <program>

  -h, --help     display this help and exit
  -V, --version  output version information and exit

For more details see nsenter(1).
