All correct.

Whenever you run env-update, it generates /etc/{csh,profile}.env, based 
on the the settings in /etc/env.d, /etc/hostname (in fact, it does a 
bunch more stuff, but that's irrelevent right now).

Why should they? You could replace the 'hades.flapper.net' in *.env with 
`cat /etc/hostname`, but if you're going to automatically generate those 
files anyway, requiring the shell to load /etc/hosname on startup is 
just more work. Granted that on a fast processor, this would be 
vanishingly small in terms of time, but it's still pointless.
