The upgrade to
|
|
.Nx
|
|
\*V is a binary upgrade; it can be quite difficult
|
|
to advance to a later version by recompiling from source due primarily
|
|
to interdependencies in the various components.
|
|
.Pp
|
|
To do the upgrade, you must have at least base.tgz on disk and
|
|
a copy of the proper netbsd.default. It will require quite a bit
|
|
of disk space to do the upgrade.
|
|
.Pp
|
|
Since upgrading involves replacing the kernel, and most of the system
|
|
binaries, it has the potential to cause data loss. You are strongly
|
|
advised to BACK UP ANY IMPORTANT DATA ON YOUR DISK, whether on the
|
|
.Nx
|
|
partition or on another operating system's partition, before
|
|
beginning the upgrade process.
|
|
.Pp
|
|
To upgrade your system, follow the following instructions:
|
|
.(bullet
|
|
Assuming you have space, load the .tgz files onto disk
|
|
some place. Then boot the floppy-144.fs image via the
|
|
method you use. Under the install system, extract the
|
|
\&.tgz files as mentioned below or read the i386 INSTALL
|
|
notes for how to use sysinst.
|
|
.It
|
|
Extract the .tgz files.
|
|
For example, to extract
|
|
.Pa base.tgz :
|
|
.Pp
|
|
.Dl # Ic "cd /"
|
|
.Dl # Ic "pax -zrvpe -f /gz.files/base.tgz"
|
|
.It
|
|
Extract all the .tgz files you want. You should carefully
|
|
work at upgrading
|
|
.Pa /etc .
|
|
There may be changes to file formats depending on what version of
|
|
.Nx*M
|
|
you are running.
|
|
.It
|
|
.Em Be careful if you are not running with security.
|
|
The \*V distribution does contain support for password encryption.
|
|
If you are upgrading from
|
|
.Nx 1.0
|
|
, it would be reasonable to save a
|
|
copy of master.passwd and remove all passwords until after you
|
|
upgrade, as
|
|
.Nx 1.0
|
|
did not ship with password encryption.
|
|
.It
|
|
Place
|
|
.Pa netbsd.default
|
|
in
|
|
.Pa /
|
|
as the file
|
|
.Pa netbsd .
|
|
.It
|
|
Reboot. (Remember,
|
|
.Pa netbsd.default
|
|
is a 9600 console line kernel. Read the last part of the new installation
|
|
part of these notes to find out how to change your default speed.)
|
|
.It
|
|
After reboot, you should make sure you check your new file systems.
