Here is an example of what the partition information will look like once
you have entered the disklabel editor. Disk partition sizes and offsets
are in sector (most likely 512 bytes) units. Make sure these size/offset
pairs are on cylinder boundaries (the number of sector per cylinder is
given in the `sectors/cylinder' entry, which is not shown here).

Do not change any parameters except the partition layout and the label name.
It's probably also wisest not to touch the `8 partitions:' line, even
in case you have defined less than eight partitions.

[Example]
8 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:    50176        0    4.2BSD     1024  8192    16   # (Cyl.    0 - 111)
  b:    64512    50176      swap                        # (Cyl.  112 - 255)
  c:   640192        0   unknown                        # (Cyl.    0 - 1428)
  d:   525504   114688    4.2BSD     1024  8192    16   # (Cyl.  256 - 1428)

This program is designed to help you put NetBSD on your disk,
in a simple and rational way.  You'll be asked several questions,
and it would probably be useful to have your disk's hardware
manual, the installation notes, and a calculator handy.
__welcome_banner_1

This program is designed to help you upgrade your NetBSD system in a
simple and rational way.

As a reminder, installing the `etc' binary set is NOT recommended.
Once the rest of your system has been upgraded, you should manually
merge any changes to files in the `etc' set into those files which
already exist on your system.

cat << \__welcome_banner_3

As with anything which modifies your disk's contents, this
program can cause SIGNIFICANT data loss, and you are advised
to make sure your data is backed up before beginning the
installation process.

Default answers are displayed in brackets after the questions.
You can hit Control-C at any time to quit, but if you do so at a
prompt, you may have to hit return.  Also, quitting in the middle of
installation may leave your system in an inconsistent state.

machine has halted, power-cycle the system to load new boot code.

This release uses the ELF binary object format. Existing (a.out) binaries
can still be used on your system after it has been upgraded, provided
that the shared libraries needed by those binaries are made available
in the filesystem hierarchy rooted at /emul/aout.

This upgrade procedure will now establish this hierarchy by moving all
shared libraries in a.out format found in /usr/lib to /emul/aout/usr/lib.
It will also move the X11 shared libraries in a.out format from previous
NetBSD/sparc X11 installation sets, if they are installed.
