Without further ado, the following was found: Issue: mount point I<B> → mount I<B> "Here, I<B> is the destination mount, and I<b> is a subdirectory path under " "the mount point I<B>. The propagation type of the resulting mount, I<B/b>, " "follows the same rules as for a bind mount, where the propagation type of " "the source mount is considered always to be private." "Here, I<A> is a mount on I<B/b>, where I<B> is the parent mount and I<b> is " "a subdirectory path under the mount point I<B>. If B<B> is shared, then all " "most-recently-mounted mounts at I<b> on mounts that receive propagation from " "mount I<B> and do not have submounts under them are unmounted."
