Further, when you boot on a serial console how do you connect gdb
over a serial console? You can't use a serial console for two things
concurrently. Then a xen-kernel debugger is useful. And yeah, that needs
standard symtabs and strtabs.
And with a kernel debugger, you don't need to worry about what John pointed
out.
