Probably. Giving more details (as in, why are you asking this? are you doing a school assignment? are you implementing lxc on a new system that will be used for shared hosting and want to find most efficient use of space?) would help you get the answers you want. When using lxc1 (old lxc-*) commands, the templates would create a cache. Containers (using the same template) created close-enough (in time) to each other would mostly be COPIES of the cache (i.e. mostly same content, use triple the space: one for the template, one for each container). With lxd and the default zfs storage pool, images would be cached as necessary, and containers (using the same image) created close-enough (in time) to each other would mostly be CLONES of the image (i.e. start with same content, sharing the SAME disk space, but then each container have their own configuration files). However if you create them several days apart, there will be a chance that the template/image has been updated, thus making the content (and the disk space used) different, even when they're using the same 'ubuntu 16.04' template/image. -- Fajar _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
