Upgrade FreeBSD 7.1 to 7.2

[Mikael Bak]

Hi list,

I would like to do a binary upgrade from 7.1 to 7.2. I've seen the
instructions here:
http://www.freebsd.org/releases/7.2R/announce.html

I've heard that it's safest to start the machine in single user mode
when doing upgrades, but I see no notice about it in the announcement.

So my question is: Is it ok to do this binary upgrade without start
single user mode first?

If no, must I reboot my machine to enter single user mode?

TIA,
Mikael
