This whole discussion is absurd.

Sorry. Maybe I shouldn't have mentioned libc here. But check the topic,
will you?

I went into this argument just on the statement that people considered a
crunchgenen /rescue to be just as safe as the tools in /bin and /sbin.
That was all that I reacted to, and if people want to disagree with me on
that one, I find no problems at all in pointing out that they are wrong.

I'm actually amazed that people don't just accept this fact. If we imagine
the disk, I can point at any number of disk blocks which can become
corrupt and I'll still be able to repair the system.
(Admittedly there are *some* disk blocks that are vital, but not every
disk block is).
If you have a crunchgenned /rescue, any broken block will stop you, no
matter which one.

How can people claim that it's just as robust is beyond me. The arguments
borders on total silliness.

As for the discussion about making everything shared, I've already given
up on that one. It will happen. I don't care.

I'll see if I can build my VAX systems totally static, if you really want
to know, and see what performance gains I get.
As for my PC, I'll probably let it follow the general flow of development,
since I have a much easier time fixing things on that machine (I have a CD
with NetBSD on that I can boot from).
