Flashrd

flashrd

flashrd is an OpenBSD installer tailored for flash-backed devices that have at least 1Gb of flash and 128Mb of RAM. Here's the project's homepage

Installing flashrd

Download the flashrd binary images.

Backup the existing flash cards using dd.

dd the new flashrd images to the existing flash cards.

Mount the flash cards or boot the flash card using qemu, modify /etc/ttys as follows:

19c19
< tty00 "/usr/libexec/getty std.9600" unknown off
---
> tty00 "/usr/libexec/getty std.9600" vt220 on secure

Add this to /flash/etc/boot.conf: (/flash is on /dev/wd0a)

set timeout 5
set tty com0

Plug the flash cards into the existing devices, boot as follows:

boot> set tty com0
switching console to com0
                         >> OpenBSD/i386 BOOT 3.02
boot> boot
booting hd0a:/bsd: 10707316+1055248 [52+360656+344597]=0xbe4014
entry point at 0x200120

Usage notes

To boot the older flash images, "boot -s" and then "/stand/rc" or "sh /etc/rc". If you need to use the network, remember to do "pfctl -d".

Once you have a serial console on the new image, copy /etc/hostname.*, /etc/ssh/*key*, and /root/.ssh/authorized_keys to the new image from the old image. Upon reboot you should be able to log in.

Files to copy from /etc:

hosts x
