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.

I found out the easy way: by trying it in a VM. You should have a VM set up for testing, too. Set a snapshot before you do anything dangerous, so you can revert to it.

That's a good idea. Thanks for the VM suggestion and link.
