You're running 3.5 on sun 4's? I thought the latest pre-4.0 OS running on
Sparcs was 3.2.

As for the upgrade: Read Sun's instructions carefully. Make sure you
understand Sun's rearrangement of the filesystem. 

You'll find that 4.0's fsck will act strangely the first time it sees a
3.5 filesystem, giving lots of "... length is xx bytes; setting to 512"
messages. Don't worry about this; nothing is wrong with your filesystem.

Keep a copy of 3.5's suntools around, if you can. Suntools under 4.0 is
bigger and slower, and a bit different.
