upgrade revision 1.1.2.2 
      1  1.1.2.2  perry The upgrade to NetBSD _VER is a binary upgrade; it would be prohibitive
      2  1.1.2.2  perry to make users upgrade by compiling and installing the _VER sources, and
      3  1.1.2.2  perry it would be very difficult to even compile a set of instructions that
      4  1.1.2.2  perry allowed them to do so.  Because of the many changes to the system, it
      5  1.1.2.2  perry is difficult and impractical to upgrade by recompiling from the sources
      6  1.1.2.2  perry and installing.
      7  1.1.2.2  perry 
      8  1.1.2.2  perry Since upgrading involves replacing the boot blocks on your NetBSD
      9  1.1.2.2  perry partition, the kernel, and most of the system binaries, it has the
     10  1.1.2.2  perry potential to cause data loss.  You are strongly advised to BACK UP ANY
     11  1.1.2.2  perry IMPORTANT DATA ON YOUR DISK, whether on the NetBSD partition or on
     12  1.1.2.2  perry another operating system's partition, before beginning the upgrade
     13  1.1.2.2  perry process.
     14  1.1.2.2  perry 
     15  1.1.2.2  perry The upgrade is done entirely `by hand.' You will need first to boot
     16  1.1.2.2  perry the new boot floppy or INSTALL kernel and use /usr/mdec/install to
     17  1.1.2.2  perry install new boot blocks. Then you may extract a new kernel and the
     18  1.1.2.2  perry distribution sets as described in section 5 of the installation
     19  1.1.2.2  perry instructions.
     20  1.1.2.2  perry 
     21  1.1.2.2  perry After this point your machine is a complete NetBSD _VER system.
     22  1.1.2.2  perry However, that doesn't mean that you're finished with the upgrade
     23  1.1.2.2  perry process.  You will probably want to update the set of device nodes
     24  1.1.2.2  perry you have in /dev.  If you've changed the contents of /dev by hand,
     25  1.1.2.2  perry you will need to be careful about this, but if not, you can just
     26  1.1.2.2  perry cd into /dev, and run the command "sh MAKEDEV all".
     27  1.1.2.2  perry 
     28  1.1.2.2  perry You must also deal with certain changes in the formats of some of
     29  1.1.2.2  perry the configuration files. The most notable change is that we now
     30  1.1.2.2  perry have an /etc/rc.conf file which describes most configuration options,
     31  1.1.2.2  perry but also the "options" given to many of the file systems in /etc/fstab
     32  1.1.2.2  perry or by hand have changed, and some of the file systems have changed
     33  1.1.2.2  perry names.  To find out what the new options are, it's suggested that
     34  1.1.2.2  perry you read the manual page for the file systems' mount commands, for
     35  1.1.2.2  perry example mount_nfs(8) for NFS.
     36  1.1.2.2  perry 
     37  1.1.2.2  perry Finally, you will want to delete old binaries that were part of
     38  1.1.2.2  perry the version of NetBSD that you upgraded from and have since been
     39  1.1.2.2  perry removed from the NetBSD distribution. Especially important, if you
     40  1.1.2.2  perry use NFS, is removing /sbin/nfsd and /sbin/nfsiod; the new versions
     41  1.1.2.2  perry of these programs are in /usr/sbin.
