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) [End of example]

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. __welcome_banner_2 fi
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.

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.
