Hello, I was wondering if it was possible for the bind mounts created under a lower layer to be exposed via overlayfs? I have attached a test script that reproduces what I'm trying to achieve: $ unshare --user --map-root-user --mount bash -xe mount-test + mkdir -p real/usr/lib + touch real/usr/lib/foo + mkdir -p stage/input + mount --bind real stage/input <-- I want to mount `real` under `input`. + ls -l stage/input drwxr-xr-x 3 root root 4096 Mar 12 11:53 usr <-- `usr` is visible. + mkdir work upper merged + mount -t overlay overlay -olowerdir=./stage,upperdir=./upper,workdir=./work ./merged + ls -Rl merged/input merged/input: total 0 <-- The `usr` directory is not passed through. I wasn't able to find anything that explicitly states it's not supported. Is something like this possible? I tried setting the mount propagation to shared, but that didn't have any effect. Thanks, Raul
