I've been using bind mounts for 20 years, they're pretty simple. Now I see there is also a move mount,

The move operation

Move a mounted tree to another place (atomically). The call is:

mount --move olddir newdir

This will cause the contents which previously appeared under olddir to now be accessible under newdir. The physical location of the files is not changed.

Sounds like a bind mount to me. What's the difference between this and binding the newdir to the olddir?

  • Seems to me that bind is like cp for mount point, and move is like mv.

    With a bind mount p->q both p & q are accessible showing the same contents. With a move mount p->q the contents are no longer accessible through p. For one...
