This way you can check if this applies. Note 'shared' in the output: grep -iP '/ /\s' /proc/$$/mountinfo ... 25 0 252:1 / / rw,relatime shared:1 - ext4 /dev/mapper/my--vg-root rw,errors=remount-ro,data=ordered ... This is usual in systemd systems, and Ubuntu is one of them. Calling unshare -m within the process context helps this. I'm forwarding this also to devel, so that we can discuss, if doing this is advisable in general.
