Again, any system that needs "recovery" tools should probably have a
kernel-with-ramdisk bootable from /. *That* is your most likely way to
recover from loss of critical system files. Think of it as a very big
statically linked binary. 8-)
A possible alternative is a special tool fileset, let's call it /recover for
the moment, which contains a crunchgen'd collection of vital system tools.
Among other things, it could contain a copy of init (to be loaded as a
fallback by the kernel), and /bin/sh....
In any case, claiming that /bin and /sbin are the "system recovery" tools is
pretty ludicrous, as those same tools still depend on several critical
files. The only *real* reason that /bin and /sbin have continued to be
statically linked is because they contain the tools necessary to locate and
mount /usr. That's all.
