The upgrade to NetBSD 1.0 is a binary upgrade; it would be prohibitive
|
||
|
|
to make users upgrade by compiling and installing the 1.0 sources, and
|
||
|
|
it would be very difficult to even compile a set of instructions that
|
||
|
|
allowed them to do so.
|
||
|
|
|
||
|
|
To do the upgrade, you must have at least base.tar.gz on disk and
|
||
|
|
a copy of the proper netbsd.sdx.yyyy. It will require quite a bit
|
||
|
|
of disk space to do the upgrade.
|
||
|
|
|
||
|
|
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
|
||
|
|
NetBSD partition or on another operating system's partition, before
|
||
|
|
beginning the upgrade process.
|
||
|
|
|
||
|
|
To upgrade your system, follow the following instructions:
|
||
|
|
|
||
|
|
Make sure your are root. Just in case the new binaries don't
|
||
|
|
run with the old kernel, make copies of several key binaries
|
||
|
|
from /bin, /sbin and /usr/bin in some directory. (Things like
|
||
|
|
sh, cp, ls, rm, tar, halt, and others.)
|
||
|
|
|
||
|
|
Extract the tar.gz files. Remember to use the --unlink
|
||
|
|
option with tar so it can replace binaries currently in use.
|
||
|
|
For example, to extract base.tar.gz:
|
||
|
|
|
||
|
|
cd /
|
||
|
|
tar -xpzf /gz.files/base.tar.gz --unlink
|
||
|
|
|
||
|
|
Extract all the tar.gz files you want. You should carefully
|
||
|
|
work at upgrading /etc. There may be changes to file formats
|
||
|
|
depending on what version of NetBSD/pc532 you are running.
|
||
|
|
|
||
|
|
BE CAREFUL IF YOU ARE RUNNING WITH SECURITY. The distribution
|
||
|
|
binaries don't support it. It would be reasonable to save a
|
||
|
|
copy of master.passwd and remove all passwords until after
|
||
|
|
you upgrade to the new security level.
|
||
|
|
|
||
|
|
Place the proper netbsd.sdX.YYYY in / as the file netbsd.
|
||
|
|
|
||
|
|
Reboot.
|
||
|
|
|
||
|
|
After reboot, you should make sure you check your new file systems.
|
||
|
|
Also, you may wish to upgrade your file systems to the new file
|
||
|
|
system format. After the install process is complete,
|
||
|
|
use "fsck -c 2" to upgrade the file systems. Read the fsck(8)
|
||
|
|
manual page for more details.
|
||
|
|
|
||
|
|
If you upgrade your file systems, you will want to make sure
|
||
|
|
you have the most recent ufs boot program if you use the
|
||
|
|
NetBSD boot program to read the kernel off a ufs file system.
|
||
|
|
Use bim(8) to remove your old boot program and install the
|
||
|
|
newest one if you are using the autoboot monitor.
