upgrade revision 1.2.4.1 
      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 older kernels may not be
     23 	  capable of running NetBSD 1.2 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 the NFS subsystem in the NetBSD 1.2
     36 	  kernel may be incompatible with your old binaries.
     37 
     38 	* Back up your pre-existing kernel and copy the 1.2
     39 	  kernel into your root partition.
     40 
     41 	* Reboot with the 1.2 kernel into single-user mode.
     42 
     43 	* Check all filesystems:
     44 
     45 		/sbin/fsck -pf
     46 
     47 	* Mount all local filesystems:
     48 
     49 		/sbin/mount -a -t nonfs
     50 
     51 	* If you keep /usr or /usr/share on an NFS server, you
     52 	  will want to mount those filesystems as well.  To do
     53 	  this, you will need to enable the network:
     54 
     55 		sh /etc/netstart
     56 
     57 	* Run the update(8) daemon, to ensure that new programs
     58 	  are actually stored on disk.
     59 
     60 		update
     61 
     62 	* Make sure you are in the root filesystem and extract
     63 	  the `base' binary set:
     64 
     65 		cd /
     66 		tar --unlink -zxvpf /path/to/base11.tar.gz
     67 
     68 	  NOTE: the `--unlink' option is _very_ important!
     69 
     70 	* Install a new boot block:
     71 
     72 		cd /usr/mdec
     73 		disklabel -B <root disk, e.g. sd0>
     74 
     75 	* Sync the filesystems:
     76 
     77 		sync
     78 
     79 	* At this point you may extract any other binary sets
     80 	  you may have placed on local filesystems, or you may
     81 	  wish to extract additional sets at a later time.
     82 	  To extract these sets, use the following commands:
     83 
     84 		cd /
     85 		tar --unlink -zxvpf <path to set>
     86 
     87 NOTE: you SHOULD NOT extract the `etc' set if upgrading.  Instead, you
     88 should extract that set into another area and carefully merge the changes
     89 by hand.
