What were you trying to do that didn't work?

I have tried testing my components using image-mode. Many of my tests failed, because useradd didn't find group called "lp". I have tried to find group on the system by getent and it found this group: 

getent group | grep lp 
  lp:x:7:

I have looked into /etc/group and didn't find it there:

cat /etc/group | grep lp
 

So I was looking for the source of the group and found this:

cat /etc/nsswitch.conf | grep group
  group:      files [SUCCESS=merge] altfiles [SUCCESS=merge] systemd

So it was probably added by nss and not found by useradd. Is there anything, that can be done?

What is the impact of this issue to you?
