getfacl does not work even for the .socket "file" in my home directory for which ~/sun works perfectly fine with permissions (and all subdirectories crated with mkdir under it).
Also like I said, ~/sun also works perfectly fine in /cygdrive/g/cygwin/ but not if I created a subdirectory with the shell's mkdir command. > Can you give us more information about where that error is coming from?
