Sure. That has nothing to do with what I'm talking about. While you can set and reset the R/O bit on a dir, it doesn't have the *meaning* of the directory being R/O. If Cygwin reports such a directory as being read-only from the POSIX perspective, certain functions would have strange ideas and return EACCES, for instance. > >Therefore the fault is not on Cygwin's side, but on Samba's side to use > >the DOS R/O bit for something different than Windows uses it on > >directories. > > Understood.

For example, a per-mount setting called dro/nodro (directory That's not the right thing to do, IMHO. That's what the default "acl" mount mode is for.
