In addition to HPA's response, I always found it kind of like a
shortcut.  Firstly, the /dev nodes generally won't persist on to
userspace, so the naming is arbitrary.  Secondly, it seems easier, in
my eyes, to check for an existing /dev/root node rather than checking
some $ROOT environment variable (whoops, it's numeric, thanks vmware -
/dev/303 doesn't exist... time to parse that out) - by this, I am
implying some sort of /init script with minimal error checking before
calling kinit (echo "Error: Root device not found...").
