NILFS, BTRFS, ... maybe provide solution for snapshots, but quota support is still missing (we need quotas on subdirectories)? And a FS independent solution would be great, so that it works on top of NFS too. So UnionFS looks good, but it does not provide real snapshots (using base + incremental change looks clumsy for our purpose). I am also not sure if quota works on UnionFS? - Dietmar _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
