upgrade revision 1.7 1 The upgrade to NetBSD _VER is a binary upgrade; it would be prohibitive
2 to make users upgrade by compiling and installing the _VER sources, and
3 it would be very difficult to even compile a set of instructions that
4 allowed them to do so. Because of the many changes to the system, it
5 is difficult and impractical to upgrade by recompiling from the sources
6 and installing.
7
8 No automated upgrade procedure exists for upgrading to release _VER for the
9 NetBSD/mac68k architecture. The current procedure is essentially to perform
10 a new install from scratch. It is hoped that there will be a good upgrade
11 procedure for future releases. Please feel free to volunteer to help
12 replace these installation tools.
13
14 The following steps outline the current upgrade procedure. These steps
15 should help ease the upgrade process. Please read these instructions
16 carefully and completely before proceeding:
17
18 1) Since upgrading involves replacing the kernel and most of the system
19 binaries, it has the potential to cause data loss. You are strongly
20 advised to BACK UP ANY IMPORTANT DATA ON YOUR DISK, whether on the
21 NetBSD partition or on another operating system's partition, before
22 beginning the upgrade process. Although the upgrade should not
23 damage your filesystem(s) in any way, you never know what may happen.
24
25 2) Download the distribution sets you want from the "mac68k/binaries"
26 subdirectory of the NetBSD _VER distribution. You will need the base
27 set and the kernel at a minimum. Be sure to download the files in
28 _binary_ mode. If you will be upgrading from within NetBSD, make sure
29 that you place the distribution sets on a filesystem you will be able to
30 reach from single-user mode.
31
32 3) Install the _VER kernel. You may either use the Installer utility
33 (included in the utils subdirectory) or install from within
34 NetBSD (the latter is recommended for speed reasons). If you choose
35 the former, proceed as you normally would. If you choose to install from
36 within NetBSD, then boot (or shutdown) into single-user mode and do the
37 following:
38
39 cd /
40 tar -zxvpf netbsd13 (substitute the full path to archive here)
41
42 There is no need to explicitly backup your old kernel since it will be
43 incapable of running many the newer binaries you are about to install.
44
45 4) If you are installing using the Installer, skip to step 5. Otherwise,
46 reboot into NetBSD in single-user mode. Run 'fsck -f' and then mount all
47 local partitions read/write. Usually 'mount -a -t nonfs' should do the
48 trick, but if you have several partitions on the same disk, take note of
49 the fact that a change in partition numbering may have moved a few of
50 your partitions around. You can do a 'disklabel sdX' (where X is a
51 drive on which you have NetBSD partitions) to see how the partitions are
52 currently layed out. It is likely that a partition has shifted into
53 'sdXd', a slot that was not available under previous releases of NetBSD.
54 If this is the case, you will need to manually mount your root partition
55 (via 'mount -w /') and edit your /etc/fstab file to reflect the new
56 partition layout. Unless you are familiar with 'ex', the easiest way to
57 fix your /etc/fstab file is probably to simply do a 'cat > /etc/fstab'
58 and type in the corrected file in its entirety.
59
60 5) Install the distribution sets. Keep in mind that the NetBSD _VER
61 distribution takes up a considerable amount more of disk space than did
62 the 1.2 or 1.2.1 distributions. If you are using the Installer, proceed
63 normally (remember that you will need to mount non-root partitions by
64 hand using the MiniShell before installing). If you are installing from
65 with NetBSD, do the following:
66
67 cd /
68 tar --unlink -zxvpf base13 (substitute the full path to the archive here)
69
70 It is crucial that you use the '--unlink' flag when invoking tar or you
71 will fail to correctly overwrite some files. Keep in mind that there is
72 no going back once you have installed the base set short of a complete
73 reinstall of an earlier distribution. Continue with the appropriate
74 command line for each of the other packages you have installed except for
75 the etc package. If you are in the Installer, open up the Minishell and
76 do the following:
77
78 cd /tmp
79 exit
80
81 Now, use the Installer to install the etc package (it will install into
82 /tmp instead of the /etc/ directory).
83
84 If you are in NetBSD, do the following instead:
85
86 cd /tmp
87 tar --unlink -zxvpf etc13 (substitute the full path to the archive here)
88
89 6) If you are in the Installer, quit it and boot into NetBSD in single-user
90 mode. From there, 'cd' to the /tmp/etc directory and compare each file
91 there with your old files in /etc. You will probably want to replace
92 some of your system configuration files, or incorporate some of the
93 changes in the new versions into yours. You should take note of the
94 following when upgrading to the etc13 set:
95
96 * The first file to pay attention to is /etc/rc.conf. This file did not
97 exist under NetBSD 1.2, but it is used to configure the rc scripts
98 under NetBSD _VER. Edit the file to your preferences, making sure that
99 you change the line that says:
100
101 rc_configured=NO
102
103 to read:
104
105 rc_configured=YES
106
107 This will enable all of the options you have configured in /etc/rc.conf.
108
109 * The next important item to take note of is the new networking
110 configuration files. If you currently have an /etc/hostname.xxN file
111 (fill in the xxN with either ae0 or sn0), you will need to convert it
112 into an ifconfig.xxN file before networking automatically works. The
113 format for the new file is simply the arguments which you would give
114 to ifconfig on the command line. The following is an example of the
115 minimal ifconfig.xxN file:
116
117 inet hostname.domain.dom netmask 0xffffff00
118
119 Read the ifconfig(8) man page for more details on arguments to ifconfig.
120 Be sure to set
121
122 auto_ifconfig=YES
123
124 in /etc/rc.conf to ensure that your network interfaces will be brought
125 up automatically on boot.
126
127 * Many of the options given to many of the file systems have changed,
128 and some of the file systems have changed names. IT IS IMPERATIVE THAT
129 YOU CHANGE ANY INSTANCES OF "ufs" IN /etc/fstab TO "ffs". To find out
130 more about different filesystem options, read the man page for the
131 associated mount command (e.g. mount_mfs(8) for MFS filesystems, note:
132 FFS type filesystems are documented in the mount(8) man page). If you
133 have not already done so, you may also need to correct /etc/fstab for
134 a shift in the partition numbering scheme. See step (4) above for more
135 details.
136
137 * You will also probably want to upgrade your device nodes at this time
138 as well. Make sure you have installed the latest MAKEDEV script (it
139 should be included in the etc set) and perform the following commands:
140
141 cd /dev
142 sh MAKEDEV all
143
144
145 7) A number of binaries have changed their locations from NetBSD 1.2.1 to
146 NetBSD _VER (most of these have moved from /sbin to /usr/sbin). A few
147 binaries have been removed. It is probably best if you scan the
148 modification dates of the files in the /sbin directory. If there are
149 files in the directory which have newer counterparts in the /usr/sbin
150 directory, it is a very good idea to remove the older files (you will
151 probably run into difficulties later if you choose not to do this).
152 You should also check the /sbin, /bin, /usr/bin/, and /usr/sbin
153 directories for old binaries that are no longer part of the NetBSD
154 distribution and delete them as well. In general, all the files in a
155 particular distribution should have similar modification dates, so
156 looking at these is a good way of determining a file's age.
157
158 8) Run 'fsck -f' to make sure that your filesystem is still consistent. If
159 fsck reports any errors, fix them by answering 'y' to its suggested
160 solutions (note: if there are a large number of errors, you may wish
161 to stop and run 'fsck -fy' to automatically answer "yes" instead).
162
163 9) Exit from single-user mode and it should continue to boot into
164 multi-user mode.
165
166 At this point you have successfully upgraded to NetBSD _VER.
