In using TRAMP to create a new file in a remote (Unix) directory, I discovered that TRAMP is not respecting the group sticky bit in that directory.
As is standard on a Unix system, the group sticky bit says that any new file created in that directory shall have the same group ownership as the directory itself. My own userid is nr, and my default group is also called nr. Because of the sticky bit, new files created on the remote host are owned by nr but have group ownership ta105. But new files created using TRAMP have group ownership nr.
How can I modify or configure TRAMP so that it respects the group sticky bit in the remote directory?
