In the source I'm looking at for useropen, I see:

 case OREAD:
  a = R_OK;
...
 case OWRITE:
     a = R_OK;

and subsequently

 if(S_ISDIR(fid->st.st_mode)){
  if(a != R_OK){
   fprint(2, "attempt by %s to open dir %d\n", fid->u->name, omode);
   *ep = Eperm;
   return -1;

which seems to indicate that it's ok to open a directory for writing as well
as reading, which I took open(5) to say was not allowed. Could some kind
soul explain? Thanks.
