Ah, good point. Like Serge pointed, I got the -n mixed up with other
lxc- commands.

Even so, I still think the blank CONTAINER column is misleading.
Does it mean that the listed processes are not part of any container ?
Like /bin/ps which prints, say the PGID column, only when selected,
wouldn't it make sense to print the CONTAINER column only when necessary ?

Thanks,
