I noticed that recent QA TPS jobs have started failing for the nfs-utils
package. The issue seems to be this:

# rpm -V nfs-utils ; echo $?
........?   /var/lib/nfs/rpc_pipefs
1

...strace shows this, which is I think, the cause of the failure:

21466 lgetxattr("/var/lib/nfs/rpc_pipefs", "security.selinux",
0xef0620, 255) = -1 EOPNOTSUPP (Operation not supported)

...this is expected, since rpc_pipefs is a mountpoint and the filesystem there
doesn't support selinux attrs. This problem doesn't seem to exist on RHEL5 and
above. Later versions don't seem to do the lgetxattr call at all.

Is this the expected?
