Couldn't you create and share a virtual file system with FUSE?

  Like SSHFS, or something custom? And how much does that help with any of those concerns?
  • yarg 2y ago
    The primary concern is trust/security. User space limits potential security impacts, and a restricted VFS could be used to prevent clients from accessing anything that they shouldn't. (Although I'm not even pretending to know whether or not this is a remotely good idea - my guess is that it isn't, but I'd like to know just how bad an idea it actually is.)

  Mounting anything requires root even if you use FUSE. There are ways to intercept writes without root and send them to another machine. Eg you could use LD_PRELOAD. But that's exactly the kind of pain in the ass that I was hoping a project named FFmpeg-over-IP would automate.

    mount doesn't require root, but even without getting into mount namespaces, this is why fusermount3 exists

      Interesting, the man page says "To allow mounting and unmounting by unprivileged users, fusermount3 needs to be installed set-uid root". Is this the default case on any distros?
      • duped 2y ago
        It's the case on all distros that distribute it, because otherwise it's useless.
