Christian,
Thanks for handling this.

Yes, that's my interpretation too -- and it was my impression from the
beginning, with your report/analysis, as I couldn't find anything we
were doing wrong with the useradd of a system account, and specially due
to this documentation statement (comment #7):
> [...] filters out those with UID values which are below a threshold
point to screen out system users [...]
Which does not cover the possible conditions for a system user (man 8
useradd):
-r, --system
Create a system account.
System users will be created with no aging information in
/etc/shadow, and their
numeric identifiers are chosen in the SYS_UID_MIN-SYS_UID_MAX range,
defined in
/etc/login.defs, instead of UID_MIN-UID_MAX (and their GID
counterparts for the
creation of groups).
Note that useradd will not create a home directory for such an user,
regardless of the
default setting in /etc/login.defs (CREATE_HOME). You have to
specify the -m options
if you want a home directory for a system account to be created.
