I’ts not very clear to me if regular user and group quota’s are supported inside a container using a ext4 dir backend and how to achieve this.
Question is similar to:
I too want to setup an ISPconfig web server in a container, which wants to set quota’s.
I used to run such setup in the past using OpenVZ with simfs, which has this user and group quota support.
Ideally I would have each container use a dedicated mounted ext4 volume as I did with OpenVZ, easily be able to move containers to other servers by attaching the volume to an other server.
I prefer not to have to use btrfs or ZFS.
