So, in the special case of a failure that specifically targets
ld.so (I suppose it, for some reason, has worse karma than than
init, sh, and all the other programs in /sbin, for the sake of
argument 8-)) or a shared lib like libc.so (who was apparently
the designer of segmented architectures in a past life -- wooo!
rack up that negative karma!), you can recover without putting
in your fixit floppy.
Seems marginal at best... you can recover from some errors, while
other errors require a tool that would let you recover from all
errors without playing learn-both-tools.
