So the mount is still visible to other processes, and doesn't exit with

I believe you need to --make-private first, *then* mount the fs. The
inheritance setting applies to whether new mounts are also mounted in
other namespaces, not whether other namespaces currently can see the mount.
I appreciate the suggestion, but it still doesn't work:
1st login window:
$ sudo unshare -m /bin/bash
# mount --make-private /mnt
mount: /mnt is not mountpoint or bad option
In some cases useful info is found in syslog - try
dmesg | tail or so.
# mount -t nfs -o ro,vers=3,tcp 10.4.5.101:/opt /mnt
# df -Th | grep mnt
10.4.5.101:/opt nfs 92G 17G 71G 20% /mnt
2nd login window, the mount is still visible:
$ df -Th | grep mnt
10.4.5.101:/opt nfs 92G 17G 71G 20% /mnt
Applying "mount --make-private /mnt" again in the 1st window still
leaves the mount visible in the 2nd window.
Thanks,
Jim
