>Description:
sysinst does not configure NetBSD correctly after doing an installation
in which serial boot blocks are selected.  The problem only arises when
using a serial speed different than 9600 bauds.

sysinst correctly configures the boot program to the chosen speed, but
does not change getty's configuration in /etc/gettytab.

Therefore, at the first boot, you see the system booting up correctly
(i.e., the kernel shows its messages, rc prints all startup items
correctly, etc.) but when you get to the login prompt, the screen gets
corrupted because the speed is changed in between.
>How-To-Repeat:
During the installation of NetBSD on a new box, select the serial boot
blocks.  Then, choose a speed different than 9600; in my case, 57600.
Finish the installation and notice how the system boots.  When you reach
getty, messages do not appear.
>Fix:
I fixed the issue by manually patching console's entry in /etc/gettytab
to use the correct speed.  sysinst should do the same automatically.

 I suspect it would be better if gettytab didn't request the baud rate
 be changed for the console.
 Editing files from sysinst is a PITA (can go badly wrong too easily).

 I'm also sure I've used a serial console at a non-standard rate and
 the stty 9600 got removed from one of the .profile scripts to make it
 work - but my memory might be faulty!
