upgrade revision 1.4.2.4
1 1.4.2.2 mellon The upgrade to NetBSD _VER is a binary upgrade; it would be prohibitive 2 1.4.2.2 mellon to make users upgrade by compiling and installing the _VER sources, and 3 1.4.2.2 mellon it would be very difficult to even compile a set of instructions that 4 1.4.2.2 mellon allowed them to do so. Because of the many changes to the system, it 5 1.4.2.2 mellon is difficult and impractical to upgrade by recompiling from the sources 6 1.4.2.2 mellon and installing. 7 1.4.2.2 mellon 8 1.4.2.3 mellon No automated upgrade procedure exists for upgrading to release _VER for the 9 1.4.2.3 mellon NetBSD/mac68k architecture. The current procedure is essentially to perform 10 1.4.2.2 mellon a new install from scratch. It is hoped that there will be a good upgrade 11 1.4.2.2 mellon procedure for future releases. Please feel free to volunteer to help 12 1.4.2.2 mellon replace these installation tools. 13 1.4.2.2 mellon 14 1.4.2.2 mellon The following steps outline the current upgrade procedure. These steps 15 1.4.2.2 mellon should help ease the upgrade process. Please read these instructions 16 1.4.2.2 mellon carefully and completely before proceeding: 17 1.4.2.2 mellon 18 1.4.2.2 mellon 1) Since upgrading involves replacing the kernel and most of the system 19 1.4.2.2 mellon binaries, it has the potential to cause data loss. You are strongly 20 1.4.2.2 mellon advised to BACK UP ANY IMPORTANT DATA ON YOUR DISK, whether on the 21 1.4.2.2 mellon NetBSD partition or on another operating system's partition, before 22 1.4.2.2 mellon beginning the upgrade process. Although the upgrade should not 23 1.4.2.2 mellon damage your filesystem(s) in any way, you never know what may happen. 24 1.4.2.2 mellon 25 1.4.2.2 mellon 2) Download the distribution sets you want from the "mac68k/binary/sets" 26 1.4.2.2 mellon subdirectory of the NetBSD _VER distribution. You will need the base 27 1.4.2.2 mellon set and the kernel at a minimum. Be sure to download the files in 28 1.4.2.2 mellon _binary_ mode. If you will be upgrading from within NetBSD, make sure 29 1.4.2.2 mellon that you place the distribution sets on a filesystem you will be able to 30 1.4.2.2 mellon reach from single-user mode. 31 1.4.2.2 mellon 32 1.4.2.2 mellon 3) Install the _VER kernel. You may either use the Installer utility 33 1.4.2.2 mellon (included in the "installation/misc" subdirectory) or install from 34 1.4.2.2 mellon within NetBSD (the latter is recommended for speed reasons). If you 35 1.4.2.2 mellon choose the former, proceed as you normally would. If you choose to 36 1.4.2.2 mellon install from within NetBSD, then boot (or shutdown) into single-user 37 1.4.2.2 mellon mode and do the following: 38 1.4.2.2 mellon 39 1.4.2.2 mellon cd / 40 1.4.2.2 mellon tar -zxvpf /path/to/kern.tgz 41 1.4.2.2 mellon 42 1.4.2.4 thorpej There is no need to backup your old kernel explicitly since it will be 43 1.4.2.2 mellon incapable of running many of the newer binaries you are about to 44 1.4.2.2 mellon install (unless, of course, you have a backup copy of your older 45 1.4.2.4 thorpej binaries and want to revert to them for some reason). However, you 46 1.4.2.4 thorpej might want to keep a backup if you are upgrading from within NetBSD just 47 1.4.2.4 thorpej in case the newer kernel has trouble booting your machine. 48 1.4.2.2 mellon 49 1.4.2.2 mellon 4) If you are installing using the Installer, skip to step 5. Otherwise, 50 1.4.2.2 mellon reboot into NetBSD in single-user mode. Run 'fsck -f' and then mount all 51 1.4.2.2 mellon local partitions read/write. Usually 'mount -a -t nonfs' should do the 52 1.4.2.2 mellon trick, but if you have several partitions on the same disk, take note of 53 1.4.2.2 mellon the fact that a change in partition numbering may have moved a few of 54 1.4.2.2 mellon your partitions around. You can do a 'disklabel sdX' (where X is a 55 1.4.2.2 mellon drive on which you have NetBSD partitions) to see how the partitions are 56 1.4.2.4 thorpej currently layed out. It is likely that a partition has shifted into the 57 1.4.2.4 thorpej 'sdXd' or 'sdXe' slots, slots that often were not available under 58 1.4.2.4 thorpej previous releases of NetBSD. If this is the case, you will need to 59 1.4.2.4 thorpej manually mount your root partition (via 'mount -w /') and edit your 60 1.4.2.4 thorpej /etc/fstab file to reflect the new partition layout. Unless you are 61 1.4.2.4 thorpej familiar with 'ex' or 'ed', the easiest way to fix your /etc/fstab file 62 1.4.2.4 thorpej is probably to simply do a 'cat > /etc/fstab' and type in the corrected 63 1.4.2.4 thorpej file in its entirety. 64 1.4.2.2 mellon 65 1.4.2.2 mellon 5) Install the distribution sets. Keep in mind that the NetBSD _VER 66 1.4.2.2 mellon distribution takes up a considerably larger amount of disk space than 67 1.4.2.2 mellon did the 1.2 or 1.2.1 distributions. If you are using the Installer, 68 1.4.2.2 mellon proceed normally (remember that you will need to mount non-root 69 1.4.2.2 mellon partitions by hand using the MiniShell before installing). If you are 70 1.4.2.2 mellon installing from within NetBSD, do the following: 71 1.4.2.2 mellon 72 1.4.2.2 mellon cd / 73 1.4.2.2 mellon tar --unlink -zxvpf /path/to/base.tgz 74 1.4.2.2 mellon 75 1.4.2.2 mellon It is crucial that you use the '--unlink' flag when invoking tar or you 76 1.4.2.2 mellon will fail to correctly overwrite some files. Keep in mind that there is 77 1.4.2.2 mellon no going back once you have installed the base set short of a complete 78 1.4.2.2 mellon re-install of an earlier distribution. Continue with the appropriate 79 1.4.2.2 mellon command line for each of the other sets you wish to install except for 80 1.4.2.2 mellon the etc set. If you are in the Installer, open up the Minishell and do 81 1.4.2.2 mellon the following: 82 1.4.2.2 mellon 83 1.4.2.2 mellon cd /tmp 84 1.4.2.2 mellon exit 85 1.4.2.2 mellon 86 1.4.2.4 thorpej Ignore the warning message this will cause. Now, use the Installer to 87 1.4.2.4 thorpej install the etc set (it will install into /tmp instead of the /etc 88 1.4.2.4 thorpej directory). 89 1.4.2.2 mellon 90 1.4.2.2 mellon If you are in NetBSD, do the following instead: 91 1.4.2.2 mellon 92 1.4.2.2 mellon cd /tmp 93 1.4.2.2 mellon tar --unlink -zxvpf /path/to/etc.tgz 94 1.4.2.2 mellon 95 1.4.2.2 mellon 6) If you are in the Installer, quit it and boot into NetBSD in single-user 96 1.4.2.2 mellon mode. From there, 'cd' to the /tmp/etc directory and compare each file 97 1.4.2.2 mellon there with your old files in /etc. You will probably want to replace 98 1.4.2.2 mellon some of your system configuration files, or incorporate some of the 99 1.4.2.2 mellon changes in the new versions into yours. You should take note of the 100 1.4.2.2 mellon following when upgrading to the NetBSD _VER etc.tgz set: 101 1.4.2.2 mellon 102 1.4.2.2 mellon * The first file to pay attention to is /etc/rc.conf. This file did not 103 1.4.2.2 mellon exist under NetBSD 1.2, but it is used to configure the rc scripts 104 1.4.2.2 mellon under NetBSD _VER. Edit the file to your preferences, making sure 105 1.4.2.2 mellon that you change the line that says: 106 1.4.2.2 mellon 107 1.4.2.2 mellon rc_configured=NO 108 1.4.2.2 mellon 109 1.4.2.2 mellon to read: 110 1.4.2.2 mellon 111 1.4.2.2 mellon rc_configured=YES 112 1.4.2.2 mellon 113 1.4.2.2 mellon This will enable all of the options you have configured in /etc/rc.conf. 114 1.4.2.2 mellon 115 1.4.2.2 mellon * The next important item to take note of is the new networking 116 1.4.2.2 mellon configuration files. If you currently have an /etc/hostname.xxN file 117 1.4.2.2 mellon (fill in the xx with either ae or sn and the X with a number), you will 118 1.4.2.2 mellon need to convert it into an ifconfig.xxN file before networking 119 1.4.2.2 mellon automatically works. The format for the new file is simply the 120 1.4.2.2 mellon arguments which you would give to ifconfig on the command line. The 121 1.4.2.2 mellon following is an example of the minimal ifconfig.xxN file: 122 1.4.2.2 mellon 123 1.4.2.2 mellon inet hostname.domain.dom netmask 0xffffff00 124 1.4.2.2 mellon 125 1.4.2.2 mellon Read the ifconfig(8) man page for more details on arguments to ifconfig. 126 1.4.2.2 mellon Be sure to set 127 1.4.2.2 mellon 128 1.4.2.2 mellon auto_ifconfig=YES 129 1.4.2.2 mellon 130 1.4.2.2 mellon in /etc/rc.conf to ensure that your network interfaces will be brought 131 1.4.2.2 mellon up automatically on boot. 132 1.4.2.2 mellon 133 1.4.2.4 thorpej * Several of the options given to many of the file systems have changed, 134 1.4.2.2 mellon and some of the file systems have changed names. IT IS IMPERATIVE THAT 135 1.4.2.2 mellon YOU CHANGE ANY INSTANCES OF "ufs" IN /etc/fstab TO "ffs". To find out 136 1.4.2.2 mellon more about different filesystem options, read the man page for the 137 1.4.2.4 thorpej associated mount command (e.g. mount_mfs(8) for MFS filesystems; note: 138 1.4.2.2 mellon FFS type filesystems are documented in the mount(8) man page). If you 139 1.4.2.2 mellon have not already done so, you may also need to correct /etc/fstab for 140 1.4.2.2 mellon a shift in the partition numbering scheme. See step (4) above for more 141 1.4.2.2 mellon details. 142 1.4.2.2 mellon 143 1.4.2.2 mellon * You will also probably want to upgrade your device nodes at this time 144 1.4.2.2 mellon as well. Make sure you have installed the latest MAKEDEV script (it 145 1.4.2.2 mellon should be included in the etc set) and perform the following commands: 146 1.4.2.2 mellon 147 1.4.2.2 mellon cd /dev 148 1.4.2.2 mellon sh MAKEDEV all 149 1.4.2.2 mellon 150 1.4.2.2 mellon 151 1.4.2.2 mellon 7) A number of binaries have changed their locations from NetBSD 1.2.1 to 152 1.4.2.2 mellon NetBSD _VER (most of these have moved from /sbin to /usr/sbin). A few 153 1.4.2.2 mellon binaries have been removed. It is probably best if you scan the 154 1.4.2.2 mellon modification dates of the files in the /sbin directory. If there are 155 1.4.2.2 mellon files in the directory which have newer counterparts in the /usr/sbin 156 1.4.2.2 mellon directory, it is a very good idea to remove the older files (you will 157 1.4.2.2 mellon probably run into difficulties later if you choose not to do this). 158 1.4.2.2 mellon You should also check the /sbin, /bin, /usr/bin/, and /usr/sbin 159 1.4.2.2 mellon directories for old binaries that are no longer part of the NetBSD 160 1.4.2.2 mellon distribution and delete them as well. In general, all the files in a 161 1.4.2.2 mellon particular distribution should have similar modification dates, so 162 1.4.2.2 mellon looking at these is a good way of determining a file's age. 163 1.4.2.2 mellon 164 1.4.2.2 mellon 8) Run 'fsck -f' to make sure that your filesystem is still consistent. If 165 1.4.2.2 mellon fsck reports any errors, fix them by answering 'y' to its suggested 166 1.4.2.2 mellon solutions (note: if there are a large number of errors, you may wish 167 1.4.2.2 mellon to stop and run 'fsck -fy' to automatically answer "yes" instead). 168 1.4.2.2 mellon 169 1.4.2.2 mellon 9) Exit from single-user mode and it should continue to boot into 170 1.4.2.2 mellon multi-user mode. 171 1.4.2.2 mellon 172 1.4.2.2 mellon At this point you have successfully upgraded to NetBSD _VER. 173
