kickstart on serial console and postinstall

[coutch]

I'm doing some PXE/kickstart installations through serial console.

my pxelinux.cfg/default has "console=tty0 console=ttyS1,9600" in the append
line.

The installation is working just fine over the serial line, but I'd like to
check the output of the postinstall as it happens.

Is there a way to get the output of the postinstall (normally on virtual
terminal #3 I think) out on the serial console ?

Thanks,
