Nope. At least not on my Debian Stretch systems including templates with 
minimal installation and customization.

No, its not. "Keine Berechtigung" means "permission denied". Which is due to 
me running reportbug as a user, not as root and /etc/default/useradd being 
restricted to root:

root at debiantest:~# LANG=C ls -l /etc/default/useradd
-rw------- 1 root root 1195 Mar 26 10:00 /etc/default/useradd


I just tried again on a minimal template:

root at debiantest:~# useradd -m test
root at debiantest:~# getent passwd | grep test
test:x:1001:1001::/home/test:

root at debiantest:~# grep -v "^#" /etc/default/useradd 
SHELL=/bin/sh

From your other mail:
> I mean for useradd, but using adduser is recommended anyway.

Sure is, still, useradd is supposed to work as well and also its the 
distribution agnostic way to add users.

Thanks,
