Can I put my container stores on an NFS share for rootless mode?

[cshamis]

I've been banging my head on this one. I have rootless containers working well in my organization. I'd like to host them on an NFS filesystem. Both NFS client and server are running RHEL9.4, specifically:

RHEL 9.4 (Plow)
linux kernel 5.14.0-427.35.1.el9_4
NFS 4.2

whenever we try to pull we always get:

Error: a network file system with user namespaces is not supported. Please use a mount_program: backing file system is unsupported for this graph driver

I've read from Dan Walsh says just move your graphroot to something other than the NFS (which I have done) ... but itstill doesn't work.

Am I missing something fundamental here? I'd love this to be as simple as "add some obscure NFS option to /etc/exports" but I doubt I'll get that lucky.
