Continuing my tour through the FAQ: i want to boot and modify one of my images, upgrading the Emulab software per [1]. To do that, i want (i think) a node booted from a copy of the image on its disk, with access to NFS-mounted testbed filesystems. According to [2], a good way to reserve a node for maintenance is: boss> nalloc emulab-ops hwdown pc1
Sorry, that FAQ entry could be more clear. The above command is great for getting a node out of the way and unavailable, but it is not a good way to get a node you want to boot and do something to. Better to create a one-node experiment in the emulab-ops project, let that experiment swapin, and then switch it to the admin MFS with: boss> node_admin on pcXXX Then you can log in and do what you need.
