Upgrading in the same RELENG without shutdown ?

Hi,

Considering that the system is like 10,000 km away,I cannot pay it a
visit when I need to boot to single mode.

So, I doeverything in multi user mode, knowing that there is no user
connected to the system (web server).

Though I do reboot every time that the procedure expects me to reboot,
event if it is rebooting in multi -instead of single- user mode.

It worked fine so far.
