Arch Linux

Description:

Installing and removing bind will make pwck and the shadow.service unit will fail with the following status:

● shadow.service - Verify integrity of password and group files

This is caused by the following line in passwd:

named:x:40:40:BIND DNS Server:/var/named:/sbin/nologin

I'm not sure what the recommended behaviour is for packages that add new users. Should they remove them again on uninstall or just print a warning that a certain user is not needed anymore?

Steps to reproduce:
* # pacman -S bind && pacman -Rn bind
* # pwck
