It’s just that ‘make-forkexec-constructor/container’ does it by default:

--8<---------------cut here---------------start------------->8---
(define (default-namespaces args)
  ;; Most daemons are here to talk to the network, and most of them expect to
  ;; run under a non-zero UID.
  (fold delq %namespaces '(net user)))
--8<---------------cut here---------------end--------------->8---

‘least-authority-wrapper’ is stricter by defaulting to ‘%namespaces’.

Ludo’.
