need help to mount rootfs with shared mode

[calvin2021y]

I am runt a rootless podman with --rootfs /app/rootfs, after start

findmnt -o PROPAGATION /
PROPAGATION
private

is there a way to start podman container with shared rootfs mount ?

Not at present, but I also see no reason we couldn't add support. Please file an RFE.

Adding --rootfs /app/rootfs:shared would be easy, or --rootfs /app/rootfs:slave

[giuseppe]

keep in mind that shared will propagate mounts only to the rootless mount namespace (the environment you get with podman unshare)

[giuseppe]

one trick you can currently use is to add a shared volume, so podman will automatically use the shared propagation for the container rootfs as well:

$ podman run -v /:/root:shared --rm fedora findmnt -o PROPAGATION /
PROPAGATION
shared
