installing new kernels

I've always been under the impression that a machine should be
in single user mode before installing a new kernel. As such,
I've always brought the machine down before removing /unix and
installing the new version there.
If a machine is in a controlled lab environment where no one
else will be logged in, is there any reason not to install a
new /unix while in multi-user mode (with me being logged in
across the ethernet)? The procedure would be something like this:
- build new kernel
- get rid of all logged in users
- cd /
- remove (or move) old /unix
- cp in new unix
- shutdown -r (or whatever to reboot)
Is there a problem with this? All the manuals, etc, always
say to be in single user. Is there a reason for that?
Thanks in advance,
Bill
