Tell me if I get this right: I told you a tool for updating the
system, not just patching it, that includes all of patchadd's
features, and more, exists and is working. Yet, you decided to go
ahead, write a new tool with less functionality that is limited to a
subset of actions when updating a system, import it to pkgsrc after a
discussion that I'm guessing didn't even take place in a public forum,
and now you're implying that you're going to shove binary patches down
the throats of all NetBSD users?

So are "list all files in a directory", "list all files in a directory
in long format", and "list all files and their inode numbers". And
yet, we have the technolog to combine all these into a single tool.

That's more overhead, and of the worst kind: people time.

You're too busy to explain why we want something one way, but you're
not too busy to implement your ideas and put them in pkgsrc?
