As per the source [0], Directory.Create() doesn't do anything.  Other
methods which accept a DirectorySecurity argument (like
Directory.SetAccessControl()) throw NotImplementedException.

In short, I don't think that'll work. :-)

Which leaves UnixDirectoryInfo.Create(FileAccessPermissions) for
creation.

Setting owner and group can be handled via
UnixFileSystemInfo.SetOwner()[1].

Setting permissions on the directory can be done via
UnixFileSystemInfo.FileAccessPermissions [2] or
UnixFileSystemInfo.Protection [3].
