pub fn create_group(group: &str, system: bool) -> ActionSpecExpand description
Create a group (sudo action-steps group-create [--system] <group>, which
runs groupadd [--system] <group>).
High risk: groups gate access to privileged resources, so creating one is a
privilege-relevant operation on par with the rest of the user/group family.
system selects a system group (GID from the system range) via --system.
