Can anyone tell me what happens when you change that setting?  That is,
what exactly does i-installer do differently when it installs software
in a different place?

I get the idea that i-installer configures software as well as putting
the files on disc.  Can I find out about the details of exactly what
configuration steps it peforms?

Aha!

(Gerben, why didn't you just tell me this months ago when I asked you?)

Is it possible to find out what's relocatable and what's not?  And is it
practical to get a bastardised setup working (I don't care how many
config files I have to hand edit just so long as I can find out which
files need working on) with teTeX and hopefully the other `big stuff'
installed somewhere other than the boot volume and those bits which
haven't any choice installed where they're compiled to work?

I thought so.

What on Earth is it for in any case?
