Quoting Dwight Engen (dwight.en...@oracle.com):

I'm not sure about this. There can be >1 entries for /. Though when
I do
lxc-unshare -s MOUNT -- /bin/sh
mount --rbind / /
mount --make-rshared /
The first / entry seems to become shared, which I wouldn't have
expected... But I suspect there's a way to get a later entry
to be shared.
