Restarting a fuse server is possible by storing the "/dev/fuse" fd and passing it to the new instance. This obviously needs support from the server. See some related discussions here: https://lore.kernel.org/all/20240524064030.4944-1-jefflexu@xxxxxxxxxxxxxxxxx/ I'm not interested in a solution that bypasses the server completely. Thanks, Miklos
