$NetBSD: upgrade,v 1.2 1998/01/09 18:47:46 perry Exp $

NetBSD _VER is the first release in which NetBSD/sun3x is available.
|
|
Therefore, there is no official upgrade path. However, there may
|
|
be some who have installed a snapshot of the port while it was still
|
|
in development. These notes are included for them.
|
|
|
|
The miniroot image contains an upgrade program which was originally copied
|
|
from the NetBSD/sun3 distribution. However, it cannot be used with
|
|
NetBSD/sun3x because it expects a NetBSD/sun3 1.2 setup.
|
|
|
|
However, while using the miniroot's upgrade program is the preferred method
|
|
of upgrading your system, it is still possible to upgrade your system
|
|
manually. To do this, follow the following procedure:
|
|
|
|
* Place _at least_ the `base' binary set in a filesystem
|
|
accessible to the target machine. A local filesystem
|
|
is preferred, since the NFS subsystem in the NetBSD _VER
|
|
kernel may be incompatible with your old binaries.
|
|
|
|
* Back up your pre-existing kernel and copy the _VER
|
|
kernel into your root partition.
|
|
|
|
* Reboot with the _VER kernel into single-user mode.
|
|
(Otherwise you can not install the boot block.)
|
|
|
|
* Check all filesystems:
|
|
|
|
/sbin/fsck -pf
|
|
|
|
* Mount all local filesystems:
|
|
|
|
/sbin/mount -a -t nonfs
|
|
|
|
* If you keep /usr or /usr/share on an NFS server, you
|
|
will want to mount those filesystems as well. To do
|
|
this, you will need to enable the network:
|
|
|
|
sh /etc/netstart
|
|
|
|
* Run the update(8) daemon, to ensure that new programs
|
|
are actually stored on disk.
|
|
|
|
update
|
|
|
|
* Make sure you are in the root filesystem and extract
|
|
the `base' binary set:
|
|
|
|
cd /
|
|
tar --unlink -zxvpf /path/to/base.tar.gz
|
|
|
|
NOTE: the `--unlink' option is _very_ important!
|
|
|
|
* Install a new boot block:
|
|
(assuming root is on /dev/rsd0a)
|
|
|
|
cd /usr/mdec
|
|
cp -p ./ufsboot /mnt/ufsboot
|
|
sync ; sleep 1 ; sync
|
|
./installboot -v /ufsboot bootxx /dev/rsd0a
|
|
|
|
* Sync the filesystems:
|
|
|
|
sync
|
|
|
|
* At this point you may extract any other binary sets
|
|
you may have placed on local filesystems, or you may
|
|
wish to extract additional sets at a later time.
|
|
To extract these sets, use the following commands:
|
|
|
|
cd /
|
|
tar --unlink -zxvpf <path to set>
|
|
|
|
NOTE: you SHOULD NOT extract the `etc' set if upgrading. Instead, you
|
|
should extract that set into another area and carefully merge the changes
|
|
by hand.
