All the entries with with_plugin set will be mounted by plugin. The interesting case is when we do the pivot-root restore. In this case we call restore callback very early (before we unmount the old tree) and ask it to create the mountpoint at temporary location. Later we move the mount to proper place. The old_root argument of the callback is where it can find files in the original mount namespace. The is_file is return-argument. Sine files and directories cannot be bind-mounted to each-other, the callback should create the mountpoint itself and report whether it created file or directory.
