The above command attempts to preserve your boot parameters, configuration files
and some programs, but isn't guaranteed not to overwrite any of those (which is why
you backed up your own programs earlier). If you want to simply clobber all the perma-
nent storage on the entire Freeway and do a completely clean install, you can use the
command
PRESERVE_CFG=no ; . /etc/rc.buildfwy
instead of the one above. If you do that, you will have to re-enter your boot parameters
and re-install any protocols that were on that Freeway before the upgrade.
If for some reason you can't telnet to your Freeway, you can connect a serial terminal to
the “Console” connector at the back of the Freeway case and use that to login and enter
the upgrade command, or you can connect an ordinary VGA monitor and keyboard to
the back of the case, and use that.
7.2.2 Freeway CDROMs “W-A” (3.1-1) or earlier
As described in Section 7.2.1 above, you should first backup anything on your Freeway
that you want to preserve. Then connect a serial console terminal to the “Freeway con-
sole” port on the back of the Freeway case, insert the CDROM into the Freeway's
CDROM drive, and reboot the Freeway. It will boot from the CDROM, and once it has
completed booting you should login as root/setup, type “6” to enter the command shell,
then type these commands, exactly as shown:
cd /etc
PRESERVE_PARTS=yes ; . /etc/rc.buildfwy
The rc.buildfwy command will warn you that it's going to overwrite things on the disk,
but you don't need to type anything more; just give it 10 minutes or so to finish, and
then you can remove the CDROM and reboot your Freeway again, and it will be using
the new software.
