processes sysusers.d directory to create system users
Opensysusers uses the files from sysusers.d directory to create system users and groups and to add users to groups, at package installation or boot time. This tool may be used to allocate system users and groups only, it is not useful for creating non-system (i.e. regular, "human") users and groups, as it accesses /etc/passwd and /etc/group directly, bypassing any more complex user databases, for example any database involving NIS or LDAP.
Opensysusers is an alternative implementation of systemd-sysusers that may work on systems with or without systemd installed.
