Serial install of DL 1.3

Hi,

I was going to try installing 1.3 but I ran into a little problem.

There is no etc-modd.tar.bz2 to add when building CF.

And therefore I can not set the security settings for Serial access.

In /etc/inittab

Enable

S0:2345:respawn:/sbin/agetty -L 115200 ttyS0 vt102

In /etc/securetty

Add

ttyS0

ttyS1

I don’t know if I can use an old etc, but I can probably create one by booting on another computer.

Kind Regards

Jacob

I've tried to improve install-on-usb script in DL 1.3 and make installation with
serial access smoother.

I have no possibility to test the changes and will be very grateful if you check
the modified script. By design, you should get completely configured serial
access after script execution.

Please let me know if something will be unusable or wrong.

Thank you,
