upgrade revision 1.3.4.1 1 1.3.4.1 is The upgrade to NetBSD 1.2 is a binary upgrade; it would be prohibitive
2 1.3.4.1 is to make users upgrade by compiling and installing the 1.2 sources, and
3 1.2 chopps it would be very difficult to even compile a set of instructions that
4 1.2 chopps allowed them to do so. Because of the various changes to the system,
5 1.2 chopps it is impractical to upgrade by recompiling from the sources and
6 1.2 chopps installing.
7 1.2 chopps
8 1.3 jtc To do the upgrade, you must have the NetBSD kernel on AmigaDOS and
9 1.3.4.1 is you must transfer the upgrade filesystem upgr-12.fs onto the swap
10 1.3 jtc partition of the NetBSD hard disk. You must also have at least the
11 1.3.4.1 is "base12" binary distribution set available, so that you can upgrade
12 1.3 jtc with it, using one of the upgrade methods described above. Finally,
13 1.3 jtc you must have sufficient disk space available to install the new
14 1.3 jtc binaries. Since the old binaries are being overwritten in place,
15 1.3 jtc you only need space for the new binaries, which weren't previously
16 1.3 jtc on the system. If you have a few megabytes free on each of your
17 1.3 jtc root and /usr partitions, you should have enough space.
18 1.2 chopps
19 1.2 chopps Since upgrading involves replacing the kernel, and most of the system
20 1.2 chopps binaries, it has the potential to cause data loss. You are strongly
21 1.2 chopps advised to BACK UP ANY IMPORTANT DATA ON YOUR DISK, whether on the
22 1.2 chopps NetBSD partition or on another operating system's partition, before
23 1.2 chopps beginning the upgrade process.
24 1.2 chopps
25 1.2 chopps To upgrade your system, follow the following instructions:
26 1.2 chopps
27 1.3 jtc Transfer the upgrade miniroot filesystem onto the hard disk
28 1.3 jtc partition used by NetBSD for swapping, as described in the
29 1.3 jtc "Preparing your System for NetBSD Installation" section above.
30 1.3 jtc
31 1.3.4.1 is Now boot up NetBSD using the 1.2 kernel using the loadbsd
32 1.3 jtc command:
33 1.3 jtc
34 1.3 jtc loadbsd -b netbsd
35 1.3 jtc
36 1.3.4.1 is If you machine has a splitted memory space, like, e.g., DraCo
37 1.3.4.1 is machines, use this instead:
38 1.3.4.1 is
39 1.3.4.1 is loadbsd -bn2 netbsd
40 1.3.4.1 is
41 1.3 jtc You should see the screen clear and some information about
42 1.3 jtc your system as the kernel configures the hardware. Note which
43 1.3 jtc hard disk device is configured that contains your root and
44 1.3 jtc swap partition. When prompted for the root device, type
45 1.3 jtc 'sd0*' (replacing 0 with the disk number that NetBSD used for
46 1.3 jtc your root/swap device). The '*' character indicates that the
47 1.3 jtc root filesystem is contained on the swap partition.
48 1.3 jtc When you reach the prompt asking you for a shell name, just
49 1.3 jtc hit return.
50 1.2 chopps
51 1.2 chopps You will be presented with some information about the upgrade
52 1.2 chopps process and a warning message, and will be asked if you wish
53 1.2 chopps to proceed with the upgrade process. If you answer
54 1.2 chopps negatively, the upgrade process will stop, and your disk will
55 1.2 chopps not be modified. If you answer affirmatively, the upgrade
56 1.2 chopps process will begin, and your disk will be modified. You may
57 1.2 chopps hit Control-C to stop the upgrade process at any time.
58 1.2 chopps However, if you hit it at an inopportune moment, your system
59 1.2 chopps may be left in an inconsistent (and possibly unusable) state.
60 1.2 chopps
61 1.2 chopps You will be asked if you wish to upgrade your file systems to
62 1.2 chopps the new file system format. If you do, reply affirmatively.
63 1.2 chopps If you don't have your file systems upgraded now, you should
64 1.2 chopps probably do it manually after the install process is complete,
65 1.2 chopps by using "fsck -c 2". Read the fsck(8) manual page for more
66 1.2 chopps details.
67 1.2 chopps
68 1.2 chopps The upgrade program will then check your root file system,
69 1.2 chopps and, if you approved, will upgrade it to the new file system
70 1.2 chopps format. It will then mount your root file system on /mnt.
71 1.2 chopps
72 1.2 chopps If your file systems are being upgraded, the upgrade script
73 1.2 chopps will copy the new fsck(8) program to your hard disk and
74 1.2 chopps upgrade your remaining file systems.
75 1.2 chopps
76 1.2 chopps The upgrade program will then mount all of your file systems
77 1.2 chopps under /mnt. (In other words, your root partition will be
78 1.2 chopps mounted on /mnt, your /usr partition on /mnt/usr, etc.)
79 1.2 chopps
80 1.2 chopps If you don't already have the NetBSD distribution sets on your
81 1.2 chopps disk, look in the installation section for information on how
82 1.2 chopps to transfer them to your disk.
83 1.2 chopps
84 1.2 chopps Once the distribution sets are transferred to your disk,
85 1.2 chopps continue here. (Obviously, if the NetBSD distribution sets
86 1.2 chopps are already on your disk, because you've transferred them
87 1.2 chopps before starting the upgrade process, you don't need to
88 1.2 chopps transfer them again now!)
89 1.2 chopps
90 1.2 chopps After the software has been transferred to the machine (or
91 1.2 chopps mounted, in the case of upgrading via NFS), change into the
92 1.3.4.1 is directory containing the "base12" distribution set. Once you
93 1.2 chopps are there, run the "Set_tmp_dir" command, and hit return at
94 1.2 chopps the prompt to select the default answer for the temporary
95 1.2 chopps directory's path name. (It should be the path name of the
96 1.2 chopps directory that you're in.)
97 1.2 chopps
98 1.3.4.1 is Run the command "Extract base12" to upgrade the base
99 1.2 chopps distribution.
100 1.2 chopps
101 1.2 chopps Repeat the above two steps for all of the sets you wish to
102 1.2 chopps upgrade. (For each, change into the directory containing the
103 1.2 chopps set, run "Set_tmp_dir" and accept the default path name, then
104 1.2 chopps run the "Extract <setname>" command.)
105 1.2 chopps
106 1.2 chopps If you were previously using the security distribution set,
107 1.2 chopps you MUST upgrade to the new version, or you will not be able
108 1.2 chopps to log in when the upgrade process is complete. Similarly, if
109 1.2 chopps you were not previously using the security set, you must NOT
110 1.2 chopps upgrade to the new version.
111 1.2 chopps
112 1.2 chopps When you are done upgrading all of the distribution sets you
113 1.2 chopps wish to upgrade, issue the command "Cleanup". It will clean
114 1.2 chopps up the installation, by remaking some system databases. When
115 1.2 chopps it is complete, you should use "halt" to halt the system.
116 1.2 chopps
117 1.3 jtc You will probably also want to copy the release "netbsd" kernel
118 1.3 jtc image to your root at some point.
119 1.3 jtc
120 1.3.4.1 is Your system has now been upgraded to NetBSD 1.2.
121 1.2 chopps
122 1.3.4.1 is After a new kernel has been copied to your hard disk, your
123 1.3.4.1 is machine is a complete NetBSD 1.2 system. However, that
124 1.2 chopps doesn't mean that you're finished with the upgrade process.
125 1.2 chopps There are several things that you should do, or might have to
126 1.2 chopps do, to insure that the system works properly.
127 1.2 chopps
128 1.2 chopps First, if you did not upgrade your file systems to the new
129 1.2 chopps file system format during the upgrade process, you may want to
130 1.2 chopps do so now, with "fsck -c 2". If you are unsure about the
131 1.2 chopps process, it's suggested that you read the fsck(8) manual page.
132 1.2 chopps
133 1.3.4.1 is Second, you will probably want to get the etc12 distribution,
134 1.2 chopps extract it, and compare its contents with those in your /etc/
135 1.2 chopps directory. You will probably want to replace some of your
136 1.2 chopps system configuration files, or incorporate some of the changes
137 1.2 chopps in the new versions into yours.
138 1.2 chopps
139 1.2 chopps Third, you will probably want to update the set of device
140 1.2 chopps nodes you have in /dev. If you've changed the contents of
141 1.2 chopps /dev by hand, you will need to be careful about this, but if
142 1.2 chopps not, you can just cd into /dev, and run the command "sh
143 1.2 chopps MAKEDEV all".
144 1.2 chopps
145 1.2 chopps Fourth, you must deal with certain changes in the formats of
146 1.2 chopps some of the configuration files. The most notable change is
147 1.2 chopps that the "options" given to many of the file systems in
148 1.2 chopps /etc/fstab or by hand have changed, and some of the file
149 1.2 chopps systems have changed names. To find out what the new options
150 1.3.4.1 is are, it's suggested that you read the manual page for the file
151 1.3.4.1 is systems' mount commands, for example mount_nfs(8) for NFS.
152 1.3.4.1 is (Note that the information for mounts of type "ffs", i.e. Fast
153 1.3.4.1 is File Systems, are contained in the mount_ffs(8) man page.)
154 1.2 chopps
155 1.2 chopps Finally, you will want to delete old binaries that were part
156 1.2 chopps of the version of NetBSD that you upgraded from and have since
157 1.3.4.1 is been removed from the NetBSD distribution. If upgrading from
158 1.3.4.1 is a NetBSD version older than 1.0, you might also want to
159 1.3.4.1 is recompile any locally-built binaries, to take advantage of the
160 1.3.4.1 is shared libraries. (Note that any new binaries that you build
161 1.3.4.1 is will be dynamically linked, and therefore take advantage of
162 1.3.4.1 is the shared libraries, by default. For information on how to
163 1.3.4.1 is make statically linked binaries, see the cc(1) and ld(1)
164 1.3.4.1 is manual pages.)
