The worst that can happen is that a sysadmin doesn't read the docs (likely) before enabling fuse on a multiuser system, and is surprised by a user doing funny things. And _then_ has to go read the docs, or google for some info. This is basically how things normally work, and I don't consider it a DoS. > and I'm woried about problems fuse + user mounts expose in other > parts of system. I'm worried too, and I'm not saying that enabling unprivileged fuse mounts is completely risk free. Nothing is, and nobody is forced to do it.
