Can’t you update it all regardless of whether you’re using it because the Linux file system leaves the old file intact and just writes a new file and updates the pointer so anything still using the old file carries on as if nothing happened and just gets the update the next time you run it?









Yeah, that’s fair. It might be possible to get incompatible versions between two different tools that interact with each other, if say one shuts down and then starts up with the new version but the other doesn’t shut down and stays on the old.
