The upgrade to OpenBSD 1.1 is a binary upgrade; it would be prohibitive
to make users upgrade by compiling and installing the 1.1 sources, and
it would be very difficult to even compile a set of instructions that
allowed them to do so. Because of the many changes to the system, it
is difficult impractical to upgrade by recompiling from the sources
and installing.
To do the upgrade, you must have the appropriate kernel-copy floppy
image on a disk, and the upgr11.fs floppy image on another. You must
also have at least the "base11" binary distribution set available,
so that you can upgrade with it, using one of the upgrade methods
described above. Finally, you must have sufficient disk space
available to install the new binaries. Since the old binaries are
being overwritten in place, you only need space for the new binaries,
which weren't previously on the system. If you have a few megabytes
free on each of your root and /usr partitions, you should have enough
space.
Since upgrading involves replacing the boot blocks on your OpenBSD
partition, the kernel, and most of the system binaries, it has the
potential to cause data loss. You are strongly advised to BACK UP ANY
IMPORTANT DATA ON YOUR DISK, whether on the OpenBSD partition or on
another operating system's partition, before beginning the upgrade
process.
To upgrade your system, follow the following instructions:
Boot your machine using of the appropriate kernel-copy floppy.
When presented with the boot prompt (the prompt begins with
"Boot" and ends with ":-"), hit return.
You will be prompted to insert a file system floppy. Remove
the kernel-copy floppy and insert the upgr11 floppy, then hit
any key to continue booting.
While booting, you will probably see several warnings. You
should be warned that no swap space is present, and that
init(8) cannot find /etc/rc. Do not be alarmed, these are
completely normal. When you reach the prompt asking you for a
shell name, just hit return.
You will be presented with some information about the upgrade
process and a warning message, and will be asked if you wish
to proceed with the upgrade process. If you answer
negatively, the upgrade process will stop, and your disk will
not be modified. If you answer affirmatively, the upgrade
process will begin, and your disk will be modified. You may
hit Control-C to stop the upgrade process at any time.
However, if you hit it at an inopportune moment, your system
may be left in an inconsistent (and possibly unusable) state.
You will be asked if you wish to upgrade your file systems to
the new file system format. If you do, reply affirmatively.
If you don't have your file systems upgraded now, you should
probably do it manually after the install process is complete,
by using "fsck -c 2". Read the fsck(8) manual page for more
details. Note that this step is only important when upgrading
from a pre-OpenBSD 1.0 release.
The upgrade program will then check your root file system,
and, if you approved, will upgrade it to the new file system
format. It will then mount your root file system on /mnt.
If your file systems are being upgraded, the upgrade script
will copy the new fsck(8) program to your hard disk and
upgrade your remaining file systems.
The upgrade program will then automatically replace the boot
blocks on your disk with newer versions, and mount all of your
file systems under /mnt. (In other words, your root partition
will be mounted on /mnt, your /usr partition on /mnt/usr, etc.)
If you don't already have the OpenBSD distribution sets on your
disk, look in the installation section for information on how
to transfer them to your disk.
If you have only one floppy drive, and don't have the disk
space to copy all of the distribution onto the hard drive, you
can do the following:
Install a kernel on the hard drive as detailed a few
paragraphs below, then boot off the hard drive. Now
you can copy and install distribution sets
incrementally from your lone floppy drive.
Once the distribution sets are transferred to your disk,
continue here. (Obviously, if the OpenBSD distribution sets
are already on your disk, because you've transferred them
before starting the upgrade process, you don't need to
transfer them again now!)
After the software has been transferred to the machine (or
mounted, in the case of upgrading via NFS), change into the
directory containing the "base11" distribution set. Once you
are there, run the "Set_tmp_dir" command, and hit return at
the prompt to select the default answer for the temporary
directory's path name. (It should be the path name of the
directory that you're in.)
Run the command "Extract base11" to upgrade the base
distribution.
Repeat the above two steps for all of the sets you wish to
upgrade. (For each, change into the directory containing the
set, run "Set_tmp_dir" and accept the default path name, then
run the "Extract <setname>" command.)
If you were previously using the security distribution set,
you MUST upgrade to the new version, or you will not be able
to log in when the upgrade process is complete. Similarly, if
you were not previously using the security set, you must NOT
upgrade to the new version.
When you are done upgrading all of the distribution sets you
wish to upgrade, issue the command "Cleanup". It will clean
up the installation, by remaking some system databases. When
it is complete, you should use "halt" to halt the system.
When the system is halted, remove the "upgr11" floppy from
the floppy drive, and replace it with the OpenBSD 1.1
kernel-copy floppy that you previously booted from. Reboot
with that floppy.
Once again, you will be prompted to insert a file system
floppy. DO NOT replace the kernel-copy floppy, just hit any
key.
Again, While booting, you may see several warnings. You may
be warned that no swap space is present, that init(8) cannot
find /etc/rc, and that one or more databases with names like
"pwd.db" cannot be found. Do not be alarmed, as, again, these
are completely normal. Hit return at the prompt asking you
for a shell name.
You will be presented with a shell prompt, at which you should
enter the "copy_kernel" command. It will ask you what
partition to copy the kernel to, and you should reply with the
name of your root partition (e.g. sd0a or wd0a).
You will be asked if you are sure that you want to copy the
kernel. Reply affirmatively, and it will check the file
system on your root partition, mount it, and copy the kernel.
Once the kernel is copied, you should use "halt" to halt the
system.
Once the system is halted, remove the kernel-copy floppy from
the floppy disk drive, and hit any key to reboot.
Your system has now been upgraded to OpenBSD 1.1.
After a new kernel has been copied to your hard disk, your
machine is a complete OpenBSD 1.1 system. However, that
doesn't mean that you're finished with the upgrade process.
There are several things that you should do, or might have to
do, to insure that the system works properly.
First, if you did not upgrade your file systems to the new
file system format during the upgrade process, and you are
upgrading from a pre-1.0 OpenBSD, you may want to do so now,
with "fsck -c 2". If you are unsure about the process, it's
suggested that you read the fsck(8) manual page.
Second, you will probably want to get the etc11 distribution,
extract it, and compare its contents with those in your /etc/
directory. You will probably want to replace some of your
system configuration files, or incorporate some of the changes
in the new versions into yours.
Third, you will probably want to update the set of device
nodes you have in /dev. If you've changed the contents of
/dev by hand, you will need to be careful about this, but if
not, you can just cd into /dev, and run the command "sh
MAKEDEV all".
Fourth, you must deal with certain changes in the formats of
some of the configuration files. The most notable change is
that the "options" given to many of the file systems in
/etc/fstab or by hand have changed, and some of the file
systems have changed names. *IMPORTANT*: ANY INSTANCES OF "ufs"
IN /etc/fstab MUST BE CHANGED TO "ffs". To find out what the
new options are, it's suggested that you read the manual page
for the file systems' mount commands, for example mount_nfs(8)
for NFS. (Note that the information for mounts of type "ffs",
i.e. Fast File Systems, are contained in the mount(8) man
page.)
Finally, you will want to delete old binaries that were part
of the version of OpenBSD that you upgraded from and have since
been removed from the OpenBSD distribution. If you are
upgrading from a pre-1.0 OpenBSD, you might also
want to recompile any locally-built binaries, to take
advantage of the shared libraries. (Note that any new
binaries that you build will be dynamically linked, and
therefore take advantage of the shared libraries, by default.
For information on how to make statically linked binaries,
see the cc(1) and ld(1) manual pages.)
