I did a lot of updates without ever being in SU mode. A lot of production class systems (the minority of them had a backup system for failover). So far I had only 1 case (as far as I can remember), where the update caused an interrupt of the services running on the system (not counting the necessary reboot after the update). This case was either the update from 3-stable to 4.1.1 or the update from 4.1.1 to 4.2 (or something like this). The cause was an incompatible change in OpenSSL without a library version bump (which wasn't a problem because of the installworld in MU mode). Even if this particular problem wasn't known in advance to me, I expected to have a 'problem' with this particular update, so the update was done at a time where a 'hickup' wouldn't have a huge impact. If you want to go the safe route, you maybe want to redefine INSTALL to "install -S" in make.conf (I did every update without redefining it so far, but maybe this will change... just to be on the safe side). And for the general audience: You should have enough free space on the disk(s) off course (specially on a softupdates enabled slice), else the installworld may fail, but this is a general problem again and not particular to a installworld in MU mode. BTW.: Everyone who updates from 4.6: watch out for old MySQL start scripts (the contain the sequence "& &&" in one line, workaround: split the line after the first '&' and remove "&&"), they will fail to start MySQL after the update to 4.7.
