upgrade revision 1.1.1.1.2.2 
      1 
      2 There is no automated upgrade program in this release.
      3 (This is the first official release for the Sun3 anyway.)
      4 However, it is possible to upgrade your system manually.
      5 
      6 Manual upgrade procedure:
      7 
      8 	* Place _at least_ the `base' binary set in a filesystem
      9 	  accessible to the target machine.  A local filesystem
     10 	  is preferred, since there may be incompatibilities
     11 	  between the NetBSD 1.1 kernel and older route(8)
     12 	  binaries.
     13 
     14 	* Back up your pre-existing kernel and copy the 1.1
     15 	  kernel into your root partition.
     16 
     17 	* Reboot with the 1.1 kernel into single-user mode.
     18 
     19 	* Check all filesystems:
     20 
     21 		/sbin/fsck -p
     22 
     23 	* Mount all local filesystems:
     24 
     25 		/sbin/mount -a -t nonfs
     26 
     27 	* If you keep /usr or /usr/share on an NFS server, you
     28 	  will want to mount those filesystems as well.  To do
     29 	  this, you will need to enable the network:
     30 
     31 		sh /etc/netstart
     32 
     33 	  NOTE: the route(8) commands may fail due to potential
     34 	  incompatibilities between route(8) and the NetBSD 1.1
     35 	  kernel.  Once you have enabled the network, mount the
     36 	  NFS filesystems.  If you use amd(8), you may or may not
     37 	  have to mount these filesystems manually.  Your mileage
     38 	  may vary.
     39 
     40 	* Make sure you are in the root filesystem and extract
     41 	  the `base' binary set:
     42 
     43 		cd /
     44 		tar --unlink -zxvpf /path/to/base11.tar.gz
     45 
     46 	  NOTE: the `--unlink' option is _very_ important!
     47 
     48 	* Install a new boot block:
     49 
     50 		cd /usr/mdec
     51 		cp -p ./ufsboot /mnt/ufsboot
     52 		sync ; sleep 1 ; sync
     53 		./installboot /mnt/ufsboot bootxx /dev/rsd0a
     54 		# Substitute your root partition here -^
     55 
     56 	* Sync the filesystems:
     57 
     58 		sync
     59 
     60 	* At this point you may extract any other binary sets
     61 	  you may have placed on local filesystems, or you may
     62 	  wish to extract additional sets at a later time.
     63 	  To extract these sets, use the following commands:
     64 
     65 		cd /
     66 		tar --unlink -zxvpf <path to set>
     67 
     68 NOTE: you SHOULD NOT extract the `etc' set if upgrading.  Instead,
     69 you should extract that set into another area and carefully merge
     70 the changes by hand.
