Not linking node.log is not ideal, but also not a critical failure. It’s better to swallow that instead of crashing.

                 log::warn!(target: "cli", "Failed to remove current log file: {err}");

             .create_new(true)
             .open(&self.next)?;
         fs::hard_link(&self.next, &self.link)?;
         if let Err(err) = fs::hard_link(&self.next, &self.link) {
             log::warn!(
                 target: "cli",
                 "Failed to create hard link from {} to {}: {err}",
                 self.next.display(),
                 self.link.display()
             );
         }

             path: self.next,
