    _______________________________________________________

Details:

in linux the ip-tool for example mounts pseudo-files from /proc over normal
files in /run/netns/... for giving a net-namespace a name.

you can achieve similar by doing following:
touch /tmp/foo
mount --bind /proc/1/ns/net /tmp/foo

(there are further relevant use-cases for such mounts)

using `find /run/netns/ "%f %i\n"` prints the inodes of the underlaying normal
files instead of those of the pseudo-files, because it uses the inode-numbers
from the getdent()-call.

using "-ls" as find-option or any other additional property, which need a
stat()-call leads to the expected inode of the pseudo-files...

at least the output should be the same with any combination of options.

if you decide to prefer the normal inodes should alaways be shown, you should
add an option to get the inodes from possibly mounted files without the need
to know a property in advance (those /proc-files always have size 0, so a
"-size 0" helps me at the moment)
