Yep, that was probably the case.

I tested in a new VM (from scratch) 0.10.0 usb install
- initially: /var/empy + bash
- guix pull + reconfigure : usermod: change shell to nologin, but home
dir stayed the same
- delete user nobody + guix system reconfigure: user nobody is back,
with /nonexistent home dir

So this looks like it is fixed, and next usb install should be good
from 1st day...
