If you wish to upgrade 5 1.2 thorpej your system by this method, simply select the `upgrade' option once 6 1.2 thorpej the miniroot has booted. The upgrade program with then guide you 7 1.2 thorpej through the procedure. The upgrade program will: 8 1.2 thorpej 9 1.2 thorpej * Enable the network based on your system's current 10 1.2 thorpej network configuration. 11 1.2 thorpej 12 1.2 thorpej * Mount your existing filesystems. 13 1.2 thorpej 14 1.2 thorpej * Extract binary sets from the media of your choice. 15 1.2 thorpej 16 1.2 thorpej * Fixup your system's existing /etc/fstab, changing the 17 1.2 thorpej occurrences of `ufs' to `ffs' and let you edit the 18 1.2 thorpej resulting file. 19 1.2 thorpej 20 1.2 thorpej * Make new device nodes in your root filesystem. 21 1.2 thorpej 22 1.5 scottr * Don't forget to extract the `kern' set from the distribution. 23 1.2 thorpej NOTE: the existing kernel WILL NOT be backed up; doing 24 1.3 jtc so would be pointless, since older kernels may not be 25 1.4 carrel capable of running NetBSD _VER executables. 26 1.2 thorpej 27 1.2 thorpej * Install a new boot block. 28 1.2 thorpej 29 1.2 thorpej * Check your filesystems for integrity. 30 1.2 thorpej 31 1.2 thorpej While using the miniroot's upgrade program is the preferred method 32 1.2 thorpej of upgrading your system, it is possible to upgrade your system 33 1.2 thorpej manually. To do this, follow the following procedure: 34 1.2 thorpej 35 1.2 thorpej * Place _at least_ the `base' binary set in a filesystem 36 1.2 thorpej accessible to the target machine. A local filesystem 37 1.4 carrel is preferred, since the NFS subsystem in the NetBSD _VER 38 1.3 jtc kernel may be incompatible with your old binaries. 39 1.2 thorpej 40 1.4 carrel * Back up your pre-existing kernel and copy the _VER 41 1.2 thorpej kernel into your root partition. 42 1.2 thorpej 43 1.4 carrel * Reboot with the _VER kernel into single-user mode. 44 1.2 thorpej 45 1.2 thorpej * Check all filesystems: 46 1.2 thorpej 47 1.3 jtc /sbin/fsck -pf 48 1.2 thorpej 49 1.2 thorpej * Mount all local filesystems: 50 1.2 thorpej 51 1.2 thorpej /sbin/mount -a -t nonfs 52 1.2 thorpej 53 1.2 thorpej * If you keep /usr or /usr/share on an NFS server, you 54 1.2 thorpej will want to mount those filesystems as well. To do 55 1.2 thorpej this, you will need to enable the network: 56 1.2 thorpej 57 1.2 thorpej sh /etc/netstart 58 1.2 thorpej 59 1.3 jtc * Run the update(8) daemon, to ensure that new programs 60 1.3 jtc are actually stored on disk. 61 1.3 jtc 62 1.3 jtc update 63 1.2 thorpej 64 1.2 thorpej * Make sure you are in the root filesystem and extract 65 1.2 thorpej the `base' binary set: 66 1.2 thorpej 67 1.2 thorpej cd / 68 1.5 scottr tar --unlink -zxvpf /path/to/base.tgz 69 1.2 thorpej 70 1.2 thorpej NOTE: the `--unlink' option is _very_ important! 71 1.2 thorpej 72 1.2 thorpej * Install a new boot block: 73 1.2 thorpej 74 1.2 thorpej cd /usr/mdec 75 1.2 thorpej disklabel -B <root disk, e.g. sd0> 76 1.2 thorpej 77 1.2 thorpej * Sync the filesystems: 78 1.2 thorpej 79 1.2 thorpej sync 80 1.2 thorpej 81 1.2 thorpej * At this point you may extract any other binary sets 82 1.2 thorpej you may have placed on local filesystems, or you may 83 1.2 thorpej wish to extract additional sets at a later time. 84 1.2 thorpej To extract these sets, use the following commands: 85 1.2 thorpej 86 1.2 thorpej cd / 87 1.2 thorpej tar --unlink -zxvpf <path to set> 88 1.2 thorpej 89 1.2 thorpej NOTE: you SHOULD NOT extract the `etc' set if upgrading. Instead, you 90 1.2 thorpej should extract that set into another area and carefully merge the changes 91 1.2 thorpej by hand. 92
