That description certainly does appear to be a bit inconsistent. Specifically step 5 says: "Drop the system into single-user mode in order to minimize problems from updating any binaries that are already running. It also minimizes any problems from running the old world on a new kernel. # shutdown now" But if you follow the commands as shown, you're still running the old kernel and just about to overwrite the old world with a new one at this point... Either Step 5 should specify '# shutdown -r now' and select 'Single User' from the boot menu, or the sentence about 'old world on a new kernel' should be amended. As to whether a reboot into single user mode is always necessary? A lot of the time it probably isn't -- if you're running -STABLE or -RELEASE, you're not upgrading over a major version change or some other large delta in versions, and you're not making any kernel configuration changes, then you're probably OK. Otherwise, if you're on -CURRENT or making significant changes then definitely test the new kernel in single user mode before installing the rest of the world. Or use ZFS boot environments.
