It doesn't? If /bin/sh is hosed, I use /bin/csh. If /bin/ls is hosed, I
use 'echo *'. If /boot/kernel/kernel gets hosed, I use
/boot/kernel.old/kernel. If a module gets hosed, I don't load it or use
the one in kernel.old. And so forth.
If libc gets hosed, *ALL* programs stop working.
So, I did not have any single point of failure for single file
corruption before. Now I do. But you claim there was not significant
increase, statistically speaking. Could you please point out what am I
missing?
