And yet that's what the user will see if it's ever printed with perror() or similar. We're pretty bad at choosing errnos; look how abused ENOSPC is: $ errno ENOSPC ENOSPC 28 No space left on device net/sunrpc/auth_gss/gss_rpc_xdr.c: return -ENOSPC; ... that's an authentication failure, not "I've run out of disc space".
