If so, we should I am not sure that would be a good idea or if it will actually be needed. I'd like to avoid adding more cases of this, especially outside init_main.c nfs server to my understanding is in no way special; nfs client would be as it can be used for the root fs. I wonder if the nfs server should use the credentials from the `prison' that triggered things off and that would be serving the data; that would probably also solve a few virtual network stack cases that are still left on my todo list. Unfortunately I'll still need stom time and probably a pencil to inhale the `new' way NFS works. /bz -- Bjoern A. Zeeb The greatest risk is not taking one.
