Thanks, seem to work only for sharepoint within / mounted as ext4 doesnt seem to work if the shared folder is inside of a tmpfs ( ad hoc created /tmp etc., )
container1.conf : added entry for /mnt [ lxc.mount.entry = /mnt /container1/rootfs/mnt none rw,rbind 0 0 ] container2.conf : added entry for /mnt [ lxc.mount.entry = /mnt /container2/rootfs/mnt none rw,rbind 0 0 ] works : mkdir -p /mnt chmod 777 -R /mnt mkdir -p /media mount --make-rbind /media /media mount --make-rshared /media mount --make-rbind /media /mnt mount --make-rslave /mnt container1.conf : added entry for /mnt pointing to /tmp/mnt [ lxc.mount.entry = /tmp/mnt /container1/rootfs/mnt none rw,rbind 0 0 ] container2.conf : added entry for /mnt pointing to /tmp/mnt doesnt work: mount -t tmpfs -o mode=01777 tmpfs /tmp mkdir -p /tmp/mnt chmod 777 -R /tmp/mnt mkdir -p /tmp/media mount --make-rbind /tmp/media /tmp/media mount --make-rshared /tmp/media mount --make-rbind /tmp/media /tmp/mnt mount --make-rslave /tmp/mnt container-2 still unmounts /tmp/mnt what ever container1 mounts in /mnt is visible on container2 found a thread where entry in fstab matters? Thanks.
