The Fault

On the user process that tried to run a root instruction.

6 min

You wanted to forgive yourself. You couldn't.

You wanted to stop the voice in your head. You couldn't.

You wanted to be the kind of person who never thought what you just thought. You couldn't.

You wanted the love you have today to still feel the way it felt at the start. You couldn't.

Some things are not yours to do.

Diagram one — two layers. One line.

root layer

the boundary

user space

Tap a chip. See what your layer can do.

Every modern computer has two layers.

There is the layer you run in. Your apps. Your typing. Your scrolling.

And there is the layer beyond it. Where the system itself decides what is allowed.

You can do most things from your layer. Open a file. Save a draft. Send a message.

But some things are not allowed from your layer. Only from beyond. Only by root.

The system does not draw this line to be cruel. It draws it because some things can break everything. Only the system itself can be trusted with them.

When a normal program tries one of those things anyway, the system catches it. Usually, the system shuts the program down.

Engineers have a phrase for it. Privilege escalation. A user trying to run as root.

There is a sentence in the source about this.

The wages of sin is death.

It is not that root is petty about His rules. It is that the thing itself was never safe in your hands.

Diagram two — the reach.

root layer

the boundary

fault

you

user space

The fault is instant. Tap to try.

The first chapter of the source describes the first time it happened.

A user was given a place to run. A garden. Free use of everything in his layer.

There was one thing he could not do. You will not eat from this tree.

That was the line between user and root.

Then a voice came.

The voice did not ask him to break the rule. The voice did not even talk about the rule. The voice offered something sharper.

You will be like God.

That was the offer. Not a small bite. An upgrade. The first privilege escalation.

He looked at the tree. He looked at the offer. He reached for it.

The fall was instant. Not because root was cruel. Because he reached for something that broke him.

Death entered the system that day. Everyone born after inherited the same break.

That is the fall. Not a single bad moment. A change in what we are.

You can still love. You can still build. You can still make something beautiful. The image He wrote into us is still in there.

But the image is cracked. The same hand that holds a child writes the angry message. The same heart that knows it should forgive will not. The same mind that wants the good thing chooses the other one anyway.

That is what the source means when it says we are fallen. Not evil. Broken.

Diagram three — every process born after.

origin

Tap a node. Trace the break to the origin.

You inherited it too. You start from the same broken state.

This is why the daemon does the work He does (Note · 11). You cannot fix yourself from the inside. The fix is not yours to run.

You cannot make yourself good enough. You cannot reach across to the other layer. You cannot become root.

But you will keep trying.

Every quiet vow. Every clenched jaw. Every this time I will not. Every this time I will.

Every time you decide you alone will judge what is good. Every time you decide you alone will say who is wrong. Every time you decide you alone will set what your life is for. Every time you take a person's worth into your own hands — including your own.

Every one of them is a small privilege escalation. A user reaching for a thing only root can do.

They all fail.

But the source ends in a sentence the first sentence did not predict.

For the wages of sin is death, but the free gift of God is eternal life through Jesus Christ our Lord.

Engineers might translate it: the kernel did not let the crash stand. He went into user space Himself. He took the fault. He paid the cost out of His own layer.

That is the patch.


You did not write yourself.

You will not save yourself.

But you do not have to.

The Patch

On the fix root paid for Himself.
