. It is possible to easily upgrade your existing .Nx*M system using the upgrade program in 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. The upgrade program will: .(enum Enable the network based on your system's current network configuration. t Mount your existing file systems. t Extract binary sets from the media of your choice. t Fixup your system's existing
a /etc/fstab , changing the occurrences of .Sy ufs to .Sy ffs and let you edit the resulting file. t Make new device nodes in your root file system under
a /dev . t Don't forget to extract the .Sy kern set from the distribution. .(Note The existing kernel .Em will not be backed up; doing so would be pointless, since older kernels may not be capable of running .Nx \*V executables. .Note) t Install a new boot block. t Check your file systems for integrity. .enum)
p 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. t Back up your pre-existing kernel and copy the \*V kernel into your root partition
q Pa / . t Reboot with the \*V kernel into single-user mode. t Check all file systems:
p .Dl # Ic "/sbin/fsck -pf" t Mount all local file systems:
p .Dl # Ic "/sbin/mount -a -t nonfs" t If you keep
a /usr or
a /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:
p
.Dl # Ic "sh /etc/rc.d/network start"
t Run the
.Xr update 8
daemon, to ensure that new programs
are actually stored on disk.
XXX: this exist anymore?
p .Dl # Ic "update" t Make sure you are in the root file system
q Pa / and extract the .Sy base binary set:
p .Dl # Ic "cd /" .Dl # Ic "pax -zrvpe -f " Ar /path/to/ Ns Ic base.tgz" t Install a new boot block:
p .Dl # Ic "cd /usr/mdec" .Dl # Ic "disklabel -B Ar root-disk" E.g.: .Ar root-disk could be .Li sd0 . .\} .Dl # Ic "cp bootsd /.bootsd" .Dl # Ic "./installboot /.bootsd bootxx \*< Ar root-disk"
p E.g.: .Ar root-disk could be
a /dev/rsd0a . .\} t Sync the file systems:
p .Dl # Ic sync t 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:
p .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)
