The upgrade to NetBSD _VER is a binary upgrade; it would be prohibitive
|
|
to make users upgrade by compiling and installing the _VER sources, and
|
|
it would be very difficult to even compile a set of instructions that
|
|
allowed them to do so. Because of the many changes to the system, it
|
|
is difficult and impractical to upgrade by recompiling from the sources
|
|
and installing.
|
|
|
|
Since upgrading involves replacing the boot blocks on your NetBSD
|
|
partition, 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.
|
|
|
|
The upgrade is done entirely `by hand.' You will need first to boot
|
|
the new boot floppy or INSTALL kernel and use /usr/mdec/install to
|
|
install new boot blocks. Then you may extract a new kernel and the
|
|
distribution sets as described in section 5 of the installation
|
|
instructions.
|
|
|
|
After this point your machine is a complete NetBSD _VER system.
|
|
However, that doesn't mean that you're finished with the upgrade
|
|
process. You will probably want to update the set of device nodes
|
|
you have in /dev. If you've changed the contents of /dev by hand,
|
|
you will need to be careful about this, but if not, you can just
|
|
cd into /dev, and run the command "sh MAKEDEV all".
|
|
|
|
You must also deal with certain changes in the formats of some of
|
|
the configuration files. The most notable change is that we now
|
|
have an /etc/rc.conf file which describes most configuration options,
|
|
but also the "options" given to many of the file systems in /etc/fstab
|
|
or by hand have changed, and some of the file systems have changed
|
|
names. To find out what the new options are, it's suggested that
|
|
you read the manual page for the file systems' mount commands, for
|
|
example mount_nfs(8) for NFS.
|
|
|
|
Finally, you will want to delete old binaries that were part of
|
|
the version of NetBSD that you upgraded from and have since been
|
|
removed from the NetBSD distribution. Especially important, if you
|
|
use NFS, is removing /sbin/nfsd and /sbin/nfsiod; the new versions
|
|
of these programs are in /usr/sbin.
