Have you tried <df> on the command line? It shows /dev/disk1 as / (the boot volume).....in my case.
Ah thanks, that was simple enough! I guess I've never explored df much other than to see what the free/used/capacity of volumes was. I hadn't noticed it listed the mount points along with the devices. Handy!
(I've typed "df -ht hfs" more times than I care to count)
