Upgrade 5.0 to 5.1

[Guy Van Sanden]

Hi Kent

Thanks for your answers!
I have one more question, the manual says to drop to single user mode
before doing buildworld, do you do this.
If I could avoid this, I could run buildworld during the night, and do
installworld when it suits me during the daytime.

Thank you very much

Guy
