upgrade revision 1.2 
      1 It is possible to easily upgrade your existing NetBSD/hp300 system
      2 using the upgrade program in the miniroot.  If you wish to upgrade
      3 your system by this method, simply select the `upgrade' option once
      4 the miniroot has booted.  The upgrade program with then guide you
      5 through the procedure.  The upgrade program will:
      6 
      7 	* Enable the network based on your system's current
      8 	  network configuration.
      9 
     10 	* Mount your existing filesystems.
     11 
     12 	* Extract binary sets from the media of your choice.
     13 
     14 	* Fixup your system's existing /etc/fstab, changing the
     15 	  occurrences of `ufs' to `ffs' and let you edit the
     16 	  resulting file.
     17 
     18 	* Make new device nodes in your root filesystem.
     19 
     20 	* Copy a new kernel onto your root partition.
     21 	  NOTE: the existing kernel WILL NOT be backed up; doing
     22 	  so would be pointless, since a NetBSD 1.0 kernel will
     23 	  not run NetBSD 1.1 executables.
     24 
     25 	* Install a new boot block.
     26 
     27 	* Check your filesystems for integrity.
     28 
     29 While using the miniroot's upgrade program is the preferred method
     30 of upgrading your system, it is possible to upgrade your system
     31 manually.  To do this, follow the following procedure:
     32 
     33 	* Place _at least_ the `base' binary set in a filesystem
     34 	  accessible to the target machine.  A local filesystem
     35 	  is preferred, since there may be incompatibilities
     36 	  between the NetBSD 1.1 kernel and older route(8)
     37 	  binaries.
     38 
     39 	* Back up your pre-existing kernel and copy the 1.1
     40 	  kernel into your root partition.
     41 
     42 	* Reboot with the 1.1 kernel into single-user mode.
     43 
     44 	* Check all filesystems:
     45 
     46 		/sbin/fsck -p
     47 
     48 	* Mount all local filesystems:
     49 
     50 		/sbin/mount -a -t nonfs
     51 
     52 	* If you keep /usr or /usr/share on an NFS server, you
     53 	  will want to mount those filesystems as well.  To do
     54 	  this, you will need to enable the network:
     55 
     56 		sh /etc/netstart
     57 
     58 	  NOTE: the route(8) commands may fail due to potential
     59 	  incompatibilities between route(8) and the NetBSD 1.1
     60 	  kernel.  Once you have enabled the network, mount the
     61 	  NFS filesystems.  If you use amd(8), you may or may not
     62 	  have to mount these filesystems manually.  Your mileage
     63 	  may vary.
     64 
     65 	* Make sure you are in the root filesystem and extract
     66 	  the `base' binary set:
     67 
     68 		cd /
     69 		tar --unlink -zxvpf /path/to/base11.tar.gz
     70 
     71 	  NOTE: the `--unlink' option is _very_ important!
     72 
     73 	* Install a new boot block:
     74 
     75 		cd /usr/mdec
     76 		disklabel -B <root disk, e.g. sd0>
     77 
     78 	* Sync the filesystems:
     79 
     80 		sync
     81 
     82 	* At this point you may extract any other binary sets
     83 	  you may have placed on local filesystems, or you may
     84 	  wish to extract additional sets at a later time.
     85 	  To extract these sets, use the following commands:
     86 
     87 		cd /
     88 		tar --unlink -zxvpf <path to set>
     89 
     90 NOTE: you SHOULD NOT extract the `etc' set if upgrading.  Instead, you
     91 should extract that set into another area and carefully merge the changes
     92 by hand.
