Hello,

I’m planning to provide interactive development environment for our data analysts.  Containers will be created from bare base images with very few modifications, will run for a very long time (practically, forever), and will never be snapshotted; somehow a container is like a python venv.  I’m feeling that dir storage may be good enough for this case, but docs says it is “a last resort”; so does it have other shortcomings than bad performance on features I will never use?

last resort? I use dir for most of my containers.

I've also used dir storage for all lxc containers

I use 'dir' backend for most of VPS I create, because of simple free
space sharing at host.
Biggest disadvantage I see in current LXC versions is that I can't limit
disk space quota per container.

Note: I use unprivileged LXC containers without LXD in the host's Ext4
filesystem.
To separate privileges, I assign different subUID:subGID ranges per each
container, but I don't know how to use this to apply disk space quotas.

Thank you, indeed I forgot about quota.  I use xfs in most cases, a project quota may be enough; but seems I would have to manage that manually somehow.

I don't know if answer from here is easy to manage:

https://github.com/lxc/lxcfs/issues/277

... and what is the path to implement for each container.
