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