if you have the fuse kernel module installed, you can run mkdir $HOME/acme acme -m $HOME/acme and acme will mount itself there via 9pfuse. in general i don't view fuse etc as stable enough to warrant throwing away $NAMESPACE. also you'd still have to deal with non-linux systems. finally, in the specific case of label: the echoing trick is sad but also works around the lack of exported file system when you connect to another machine via ssh. (in plan 9, if you cpu somewhere rc can still find the terminal's /dev/label. not so on linux, even in the supposed presence of usable per-process name spaces.) russ
