Make installworld in single-user mode all the time?

Hi,
I'd like to patch a production server, with about 10 jails, running FreeBSD
6.0 Release, in order to get FreeBSD 6.0-p6.
Since this server is being hosted on a remote location, rebooting in
single-user mode before doing the installworld requires me to move to the
hosting center.
Documentation mentions that a reboot in single-user mode is necessary. But
on the opposite, /usr/src/UPDATING says:
> Also, when doing a major release upgrade, it is required that
> you boot into single user mode to do the installworld.
Since this is no "major release upgrade", does that mean I can do the
installworld in multi-user mode?
I have tested that on a smaller test server yesterday evening, I have even
done the installworld in running jails, and it worked just fine. Was I lucky
maybe?
Does anyone have a definitive guide to update FreeBSD correctly?
Here is what I did:
----------
1) Cleaning
> cd /usr/obj
> chflags -R noschg *
> rm -rf
2) Buildworld & Kernel
> cd /usr/src
> make buildworld (/usr/src/UPDATING mentions we should avoid the -j option)
> make kernel KERNCONF=<MY_KERNEL_CONF>
4) When doing a major release upgrade:
> reboot in single-user mode
> fsck -p
> mount -u /
> mount -a -t ufs
> swapon -a
> adjkerntz -i
6) Installworld
> cd /usr/src
> mergemaster -p
> make installworld
> mergemaster
7) Update jail1
> mergemaster -p -D /usr/jails/my_jail1
> make installworld DESTDIR=/usr/jails/my_jail1
> mergemaster -D /usr/jails/my_jail1
8) Update jail2
> mergemaster -p -D /usr/jails/my_jail2
> make installworld DESTDIR=/usr/jails/my_jail2
> mergemaster -D /usr/jails/my_jail2
9) Reboot
----------
