It is possible to easily upgrade your existing

|
|
the same steps as the miniroot upgrade program.

|

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 r_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.

.Ss2 Manual upgrade
|
|
.
|
|
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 / .
|

|

Extract and install a new boot block:

Make sure you install the bootstrap program distributed with this version of
|
|
.Nx*M .

|
|
.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.tgz
|
|
.if r_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.
