Using the installer, it’s possible to create a system config without any
non-root user accounts. That’s a problem because then users end up
creating their account manually with ‘useradd’, which gets things wrong,
To reproduce the issue, in the user page of the installer, add an
account for user “root”. That’s enough to fool this check:
(run-error-page (G_ "Please create at least one user.")
This “root” account is then ignored:
(define (users->configuration users)
,@(filter-map (lambda (user)
;; Do not emit a 'user-account' form for "root".
(and (not (string=? (user-name user) "root"))
… and that’s how you end up with a config without normal user accounts.
To address that, maybe ‘run-user-add-page’ should explicitly reject
