I noticed in /etc/inittab that it has this line:

#   0 - halt (Do NOT set initdefault to this)

It makes sense, but what if it did get set to 0 or 6?  Is there a way to
boot to single-user mode anyway to edit the file and change it to a correct
value?  What if it is set to a negative number or a value > 6?  Does it
default to a valid value.
