This all seems very subjective. Different people will have different
thoughts on what is "essential" for recovery in the situation where
/usr can't be mounted. Many of these arguments are moot anyway,
because nowadays if as system gets hosed to the extent that /usr can't
be mounted, the most effective way to recover is to boot the machine
in question with a live CD or USB and have the full range of tools
accesible to diagnose the problem.
