Hello Fans,

Why most process have 'ns' file with entryes:
    bind / /
    bind /net /net
    bind /n /n
This is artifactes or some special functionality?

Where is sane way to use proc fs:
'#p/34/ctl' or '/proc/34/ctl'

This sets up the first entry of a union mount.
In older versions you couldn't bind -a or -b
until you had explicitly started a mount point
using something like the above, but now the
kernel does them for you when necessary.

Almost always use /proc.  If you use #p then the tool
does not play well with others like snapfs or
import remote-machine /proc.
