This is a great opportunity to integrate ZFS-based BEs (boot
environments) into the workflow. They allow you to easily
revert back changes caused by updates if required.

This is also possible, and often a good suggestion, if you
can actually create such a "secondary environment"; if you
have to do everything in "live mode", BEs are probably the
best solution.
