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