Message:

VBoxGuest-netbsd.c: bugref:8547: if /dev/vboxguest already exists,
print a message with the major we've got and ask the user to check the
existing node.

Since NetBSD doesn't yet have a major reserved for vboxguest, the
(first free) major we get will change when new devices are added, so
an existing /dev/vboxguest may now point to some other device,
creating confusion (tripped me up a few times).
