    Ie, let's do things the same way we did in 1994? Other things have
    changed since then, hard drives and typical root partitions are much
    bigger, and Tim estimated the total bloat from this as 64k. Maybe
    earlier, pre-/rescue, you couldn't recover from damaged files in the
    root partition without a CD/floppy/NFS, it doesn't mean you should not
    have that capability in /rescue.

    For a *lot* of people today (like home users), an up-to-date FreeBSD
    CD or floppy or a second machine to create the disk on may not be
    handy (and forget about NFS), but a network connection may still be
    available. This applies equally if the trashed file is in /lib[exec].
    I don't understand this argument of "we have never been able to do
    this, therefore we shouldn't do this now even if we are able to".
