This is necessary to fully control mount options on remount by command line. In previous versions the bind flag has been always applied and it was impossible to re-define mount options without interaction with the bind semantic. This *mount* behavior does not affect situations when "remount,bind" is specified in the _/etc/fstab_ file. +Since util-linux 2.39, *mount* may use the new kernel mount API if it is available. This new kernel interface provides a more precise way to work with mountpoint attributes. For example, the *-o bind,rw* operation will create a read-write node even if the original node was read-only. This was impossible with the old classic mount(2) syscall, where the read-only VFS flag was inherited from the original node. + === The move operation Move a *mounted tree* to another place (atomically).
