With that said, some networking work is being done this cycle and we will try to address this.

I have the usr.bin.man profile enforced, and home directories in NFS. The log excerpt copied below is the result of a single invocation of "man ls" by an unprivileged user. (The program did display the man page correctly to the user.) It does not seem appropriate for AppArmor to report the man(1) program as having attempted to contact the NFS server directly, when it only tried to access an NFS-served file in the normal way. "man" is not a network-aware program and the log below misleadingly implies otherwise. ---------------- Jul 30 17:38:35 darkstar kernel: [69963.052243] nfs: RPC call returned error 13 Jul 30 17:38:35
