I know about symlinks, but there are cases where they don’t work exactly the same as a bind mount, e.g. in a chroot.
Yes, but the main reason I want to completely remove the master mount is, sometimes I’ll do something like “sudo find / -type f | [other processing commands]” and then have to filter out the master mount, every time I do it. Just gets tedious, and was looking for a cleaner way.
And partly, what I described was an experiment… “Can I do it.” If it’s useful, I’ll use it, if not I’ll do something else.
