Thanks, Karel.

A follow-up question. There was one piece of the unshare(1) examples
that I did not try to rework, because I simply don't understand it:

       Establish  a  persistent  mount  namespace  referenced by the bind
       mount /root/namespaces/mnt.  This example shows a  portable  solu‐
       tion,  because  it  makes sure that the bind mount is created on a
       shared filesystem.

           # mount --bind /root/namespaces /root/namespaces
           # mount --make-private /root/namespaces
           # touch /root/namespaces/mnt
           # unshare --mount=/root/namespaces/mnt

I think you wrote this example. What does the sentence "This example shows
a portable solution, because it makes sure that the bind mount is created
on a shared filesystem" mean? I think this needs clarification, and I'd try
to do so, but it's not clear to me what the sentence is trying to say.

Thanks,

Michael
