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