It may be possible to easily upgrade your existing NetBSD/pmax system
|
|
using the upgrade program in the miniroot.
|
|
|
|
NOTE: this has not been tested and should be done with caution,
|
|
after backing up your system.
|
|
|
|
If you wish to upgrade your system by this method, simply select
|
|
the `upgrade' option once the miniroot has booted. The upgrade program
|
|
with then guide you through the procedure. The upgrade program will:
|
|
|
|
* Enable the network based on your system's current
|
|
network configuration.
|
|
|
|
* Mount your existing filesystems.
|
|
|
|
* Extract binary sets from the media of your choice.
|
|
|
|
* Fixup your system's existing /etc/fstab, changing the
|
|
occurrences of `ufs' to `ffs' and let you edit the
|
|
resulting file.
|
|
|
|
* Make new device nodes in your root filesystem.
|
|
|
|
* Copy a new kernel onto your root partition.
|
|
NOTE: the existing kernel WILL NOT be backed up; doing
|
|
so would be pointless, since a NetBSD 1.1 kernel will
|
|
not work correctly with all NetBSD 1.2 executables.
|
|
|
|
* Install a new boot block.
|
|
|
|
* Check your filesystems for integrity.
|
|
|
|
While using the miniroot's upgrade program is the preferred method
|
|
of upgrading your system, it is 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 there may be incompatibilities
|
|
between the NetBSD 1.2 kernel and older route(8)
|
|
binaries.
|
|
|
|
* Back up your pre-existing kernel and copy the 1.2
|
|
kernel into your root partition.
|
|
|
|
* Reboot with the 1.2 kernel into single-user mode.
|
|
|
|
* Check all filesystems:
|
|
|
|
/sbin/fsck -p
|
|
|
|
* 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
|
|
|
|
NOTE: the route(8) commands may fail due to potential
|
|
incompatibilities between route(8) and the NetBSD 1.2
|
|
kernel. Once you have enabled the network, mount the
|
|
NFS filesystems. If you use amd(8), you may or may not
|
|
have to mount these filesystems manually. Your mileage
|
|
may vary.
|
|
|
|
* Make sure you are in the root filesystem and extract
|
|
the `base' binary set:
|
|
|
|
cd /
|
|
tar --unlink -zxvpf /path/to/base12.tar.gz
|
|
|
|
NOTE: the `--unlink' option is _very_ important!
|
|
|
|
* 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.
