It is possible to easily upgrade your existing .Nx*M system using the upgrade program in the miniroot or by manually performing the same steps as the miniroot upgrade program. . .Ss2 Upgrading using the miniroot . If you wish to upgrade your system by this method, simply select the .Sy upgrade option once the miniroot has booted. The upgrade program with then guide you through the procedure. .if \n[hp300] \{\ While you can boot the miniroot using the same methods described above for a fresh install of .Nx*M there are easier and less intrusive options since your disk is already labeled and bootable. The easiest is to dump the miniroot to your swap partition and boot from that. .(enum Download the files you'll need to upgrade .Pp In particular, make sure you have on your locally mounted file systems .Pa base.\*[setsuffix] and .Pa miniroot.fs.gz .It Boot your \*M into .Sq "single-user mode" : .Pp Follow the instructions in the section above on .Sx Chosing a kernel location and type .Li -s at the prompt. .It Extract and install a new boot block: .Pp Make sure you install the bootstrap program distributed with this version of .Nx*M . .(disp .No # Ic "tar -xpvzf base.\*[setsuffix] ./usr/mdec" .No # Ic "disklabel -B -b ./usr/mdec/uboot.lif " Ar root-disk .disp) E.g.: .Ar root-disk could be .Li sd0 or .Li rd0 .

While using the miniroot's upgrade program is the preferred method of upgrading your system, it is possible to upgrade your system manually. To do this, follow the following procedure: .(enum Place .Em at least the .Sy base binary set in a file system accessible to the target machine. A local file system is preferred, since the NFS subsystem in the .Nx \*V kernel may be incompatible with your old binaries. .It Back up your pre-existing kernel and copy the \*V kernel into your root partition .Pq Pa / . .ie \n[hp300] \{\ .It Extract and install a new boot block: .Pp Make sure you install the bootstrap program distributed with this version of .Nx*M . .(disp .No # Ic "tar -xpvzf base.\*[setsuffix] ./usr/mdec" .No # Ic "disklabel -B -b ./usr/mdec/uboot.lif " Ar root-disk .disp) E.g.: .Ar root-disk could be .Li sd0 or .Li rd0 . .\} .It Reboot with the \*V kernel into single-user mode. .It Check all file systems: .Pp .Dl # Ic "/sbin/fsck -pf" .It Mount all local file systems: .Pp .Dl # Ic "/sbin/mount -a -t nonfs" .It If you keep .Pa /usr or .Pa /usr/share on an NFS server, you will want to mount those file systems as well. To do this, you will need to enable the network: .Pp .Dl # Ic "sh /etc/rc.d/network start" .It Make sure you are in the root file system .Pq Pa / and extract the .Sy base binary set: .Pp .Dl # Ic "cd /" .Dl # Ic "pax -zrvpe -f" Em /path/to/ Ns Ic base.\*[setsuffix] .if \n[mvme68k] \{\ .It Install a new boot block: .Pp .Dl # Ic "cd /usr/mdec" .Dl # Ic "cp bootsd /.bootsd" .Dl # Ic "./installboot /.bootsd bootxx \*<" Ar root-disk .Pp E.g.: .Ar root-disk could be .Pa /dev/rsd0a . .\} .It Sync the file systems: .Pp .Dl # Ic sync .It At this point you may extract any other binary sets you may have placed on local file systems, or you may wish to extract additional sets at a later time. To extract these sets, use the following commands: .Pp .Dl # Ic "cd /" .Dl # Ic "pax -zrvpe -f" Ar path_to_set .enum) .(Note You .Em should not extract the .Sy etc set if upgrading. Instead, you should extract that set into another area and carefully merge the changes by hand. .Note)
