Subject: Differences between SunOS 4.1.1 Rev A and Rev B.


Dear Mr. Hoover,

In regard to your inquiry about differences between
SunOS 4.1.1 Rev A and Rev B, differences between
the two operating systems are extremely minimal.

Basically, the operating system between the two versions
are the same. No bugfixes, patches, or the like were
incorporated in 4.1.1 Rev B.

The main change in Rev B can be seen on pre-installed
systems that come from the factory. Automatic scripts
are run when one powers on a pre-installed system. These
automatic scripts allow easy configurations of systems
that are to be added to the network. These scripts ask
the user if the machine is connected to the internet, what
IP address will the machine use, what NIS domain does it
belong to, and the like.

Files like the rc files in /etc, were changed to make them
a little more verbose on bootup.

For a detailed list of what files were changed in Rev B, you can
take a look at the file /etc/install/chaged_in_revb.

> I include this file at the end. - Kevin

If you have any questions or concerns, feel free to call or
send electronic mail.

I will leave the service order open till the end of tomorrow.
If I don't hear from you by then, I will assume that you are
satisfied, and that I will close the service order at that point.

Thank you.
