Running nfs-ganesha 4.0.12 in a Debian Bookworm container, I get mount failures mount -t nfs -o proto=tcp,vers=4 localhost:/exports /mount_nfs mount.nfs: mounting localhost:/exports failed, reason given by server: No such file or directory from within the container and the host operating system when I've exposed port 2049 for NFS v4 although I've exported the directory and the ganesha log output reflects this. /exports is the root of an ext4 file system Any ideas? The failure mode is the same if I try mounting a directory which does not exist and is not exported.
