Hi !
=i think everybody knows bind mounts.
=i can do:
=touch /otherpath/dummyfile
mount -bind /path/file /otherpath/dummyfile
=so /path/file becomes accessible via /otherpath/dummyfile - dummyfile h=
as the same size as file after successful bind-mount

i can loopback-mount /otherpath/dummyfile to /otherpath/mnt if file/dum=
myfile contains a filesystem

when i export /otherpath via nfs (crossmnt), from the client side i can=
access the contents of the filesystem inside file/dummyfile via /otherpath=
/mnt - but i cannot access the contents of dummyfile itself, i.e. the bind= -mount seems to get lost on export.

can someone tell if this is expected behaviour or if this is a bug ?

The NFS client will not cross a mount point unless the target is a directory. That is not a bug, it is expected behaviour. =
