Has anyone else done this? Should this be possible in the first place? Thanks, Actually it does not work even after solving module issue. I asked about this very issue at the end of last year (I think), but no one answered. It looks like knfsd threads are working in "global" (i.e host) namespace, not in the container namespace, or the said namespace isn't being set up correctly in the kernel. In any way, nfs service needs to be "containerized" properly before being useful inside a container, which is not done currently, it seems. /mjt _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
