It's not about rsync exactly. The problem is that I'm missing the context a bit. I take it the permissions are supposed to be inherited from the ".." dir, basically. The ".." dir has been created by non-Cygwin means, right? The "." dir has been created by Cygwin already it seems, but what permissions were desired? Does it match the expectations or not? The "dir1" and "dir2" directories both have been created by Cygwin, but they are somehow totally wrong. I don't see how this could occur, even in case the ACL sorting fails at creation time. Btw., the getfacl output of dir1 and dir2 don't seem to match the icacls output. The groups are different. I wonder if I can create a similar scenario.
