I advise against calling your boot device "System", for obvious reasons...
a) There is normally a drawer inside SYS: that is already called System (you'll find Format in there, amongst a few other things)
b) If you try fiddling with the Resident command, you will find that there is a part of the internals called SYSTEM
This makes for possible confusion, at least for me if not for the machine. That is why I don't like naming a drive "System:" as I don't like the idea of having to type "System:System/command" :lol:
