Personally i have been bitten once on FreeBSD 3 or 4.
There had been changes 
in the kernel NFS stuff, i rebooted inadvertently multiuser,
instant panic when mounting NFS shares. Rebooting 
single user should be a required step in the upgrade procedure,
unless it is absolutely impossible (collocated machine) and
in this case i suspect no reboot at all is less risky. Even
if the make installworld doesn't succeed completely, there is good chance
that a reboot to multiuser will work and allow to do it a second time.
