It should be. Someone ;-) should investigate. I feel like it's been done before...

Note to self:

The only user installed by any extant nodeballs was 113. Users 112 and 111 were not, afaict.

(The only other NPC users after 113 were 519 and 827, and they were not installed from nodeballs either.)

The significance of this is that, if we do create a "safe" copy of the nodebase, we can probably safely delete all users except root.
