[PATCH 1/1] runqemu-internal: add "console=ttyS0" to ramfs image kernel parameters

[Chen Qi]

We need this kernel command parameter so that when we start a ramfs
image, we can actually get some output. Although we can make this
happen by specifying the 'bootparams' for the 'runqemu' command, it's
better to make this the default behaviour.

I think so.
Notice in runqemu scripts, if '-nographic' is supplied to the qemu 
command, then 'console=ttyS0' is supplied to the '-append' option. This 
is the behaviour for the 'nographic' parameter for the 'runqemu' 
command. The exception is the case of starting a ramfs image. And this 
patch fixes this.

Thanks,
