Emulab FAQ: Testbed Operations: How do do you create special experiments with no ns file?
There are special experiments with no ns file that are used as containers for nodes in various states, for example emulab-ops/reloading.
These are created using the beginexp form without specifying the ns file, with the red dot on. Red dot allows you to keep the ns file unspecified.
